ShellWindowTracker: complete WM_CLASS fix

Browse Source 
Chromium (but not google-chrome) has a StartupWMClass in the desktop
file, so we must match the instance part first to have chrome
web apps working.
Also, we must take care of apps without a wm_class or instance at
all.

Note that chromium (but not google-chrome!) includes a StartupWMClass=chromium
in their .desktop file, so we must match the instance first.
Also note that in the good case (regular gtk+ app without hacks), instance and
class are the same except for case and there is no StartupWMClass at all.
