    clutter/gesture-action: Cancel gesture when disabling the action
    
    Like the click action, it makes sense to cancel the ongoing gesture
    when the action is disabled. Do so by overriding our new friend,
    ClutterActorMeta.set_enabled, and canceling the gesture when disabling
    the action.
