    video-texture: Fix a circular dependency not breaking on unref()
    
    VideoTexture -> GstPipeline -> VideoSink -> VideoTexture
    
    Break the circular dependency by putting clutter_gst_player_deinit() in
    the dispose.
    This means that we need to make clutter_gst_player_deinit() idempotent
    as well.
