gnome-shell-extension-prefs supports opening a specific extension's preferences directly from the command line by passing the UUID. However this broke when extension loading was changed to be processed asynchronously, as no extension has been loaded when the command line argument is processed. Fix by deferring opening the extension's preferences until all extensions have been loaded. https://bugzilla.gnome.org/show_bug.cgi?id=694858
