    Set the application flag to be able to override the app id
    
    This allows to override the application ID from the command
    line with --gapplication-app-id, which has been introduced in
    GLib 2.48. This is useful when modifying GNOME Weather in
    GNOME Builder using the flatpak tools and run the modified
    application and the original one at the same time.
