    GtkApplication: Lack of optional components shouldn't warn
    
    When running uninstalled tests with GtkApplication on an autobuilder with
    a fake session bus, warnings will cause the tests to abort. The GNOME
    session manager, the Xfce session manager, and the Inhibit portal are all
    not needed for normal operation of GTK, so we should not log warnings if
    they are not found.
    
    As well as not being present on a fake session bus, it's also not
    expected that they'll be present on all platforms.
