    testsuite: don't use gtk_test_init(), use g_test_init()
    
    Using g_test_init() is fine for test-action-info-store.c, it doesn't use
    GTK+.
    
    gtk_test_init() fails in Flatpak:
    
    (./test-action-info-store:5): dbind-WARNING **: 18:27:29.148: Couldn't
    connect to accessibility bus: Failed to connect to socket
    /tmp/dbus-ZhFnAWvs9F: Connection refused
