GMenu's TreeEntries return an AppInfo that is created from the .desktop filename, not from a desktop ID as expected by the AppSystem. As a result, g_app_info_get_id() will simply return the file's basename, which only matches the desktop ID if no prefix-to-subdirectory mapping as described in the menu spec is involved. Fix this by basing the app lookup on the entry's desktop ID instead of the AppInfo. https://bugzilla.gnome.org/show_bug.cgi?id=759004
