window-tracker: check WM_CLASS for sandboxed apps before the app's ID

For sandboxed apps, the shell needs to consider the app's ID when matching its windows against the right .desktop file, but that check can't be done before having attempted to match using the WM_CLASS property of the app's window, otherwise apps installing multiple desktop files (e.g. LibreOffice) will always match every single window against the same .desktop file, ignoring hints such as the StartupWMClass key. This commit moves the call to get_app_from_sandboxed_app_id() after get_app_from_window_wmclass() and before get_app_from_window_pid(), so that we only rely on the sandboxed app's ID when no match has succeed using the WM_CLASS property, but before checking by PID to prevent wrong groups that could be created when the PID of the app inside the sandbox matches the one from a process outside of it. Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/219

 Our goal is to have all JavaScript code in GNOME follow a consistent style. In
 a dynamic language like JavaScript, it is essential to be rigorous about style
 (and unit tests), or you rapidly end up with a spaghetti-code mess.

+Summary
+-------
+
+* Do not edit the CSS directly, edit the source SCSS files and the CSS files will be generated
+  automatically when building with meson + ninja and left inside the build directory to be
+  incorporated into the gresource XML (you'll need to have sassc installed).
+
+How to tweak the theme
+----------------------
+
+Adwaita is a complex theme, so to keep it maintainable it's written and processed in SASS, the
+generated CSS is then transformed into a gresource file during gtk build and used at runtime in a 
+non-legible or editable form.
+
+It is very likely your change will happen in the _common.scss file. That's where all the widget 
+selectors are defined. Here's a rundown of the "supporting" stylesheets, that are unlikely to be the 
+right place for a drive by stylesheet fix:
+
+_colors.scss        - global color definitions. We keep the number of defined colors to a necessary minimum, 
+                      most colors are derived from a handful of basics. It is an exact copy of the gtk+ 
+                      counterpart. Light theme is used for the classic theme and dark is for GNOME3 shell 
+                      default.
+
+_drawing.scss       - drawing helper mixings/functions to allow easier definition of widget drawing under
+                      specific context. This is why Adwaita isn't 15000 LOC.
+
+_common.scss        - actual definitions of style for each widget. This is where you are likely to add/remove

-## Summary
-
-Do not edit the CSS directly, edit the source SCSS files and the CSS files
-will be generated automatically when building with meson + ninja and left
-inside the build directory to be incorporated into the gresource XML (you'll
-need to have sassc installed).
-
-## How to tweak the theme
-
-Adwaita is a complex theme, so to keep it maintainable it's written and
-processed in SASS, the generated CSS is then transformed into a gresource
-file during gtk build and used at runtime in a non-legible or editable form.
-
-It is very likely your change will happen in the [_common.scss][common] file.
-That's where all the widget selectors are defined. Here's a rundown of
-the "supporting" stylesheets, that are unlikely to be the right place
-for a drive by stylesheet fix:
-
-| File                     | Description       |
-| ------------------------ | ----------------- |
-| [_colors.scss][colors]   | global color definitions. We keep the number of defined colors to a necessary minimum,  most colors are derived from a handful of basics. It is an exact copy of the gtk+ counterpart. Light theme is used for the classic theme and dark is for GNOME3 shell default. |
-| [_drawing.scss][drawing] | drawing helper mixings/functions to allow easier definition of widget drawing under specific context. This is why Adwaita isn't 15000 LOC. |
-| [_common.scss][common]   | actual definitions of style for each widget. This is where you are likely to add/remove your changes. |
-
-You can read about SASS on its [web page][sass-web]. Once you make your
-changes to the [_common.scss][common] file, you can run ninja to generate the
-final CSS files.
