    gdm: Try harder to move focus to the first user
    
    _moveFocusToItems seems to be called to early causing
    clutter_actor_grab_key_focus not to be called.
    
    So queue another attempt with BEFORE_REDRAW priority when
    this happens to make sure we actually move the focus sucessfully.
