Crash when resizing window during conference call

Make a conference call and resize the main window in order to go into compact-mode, the client may crash. This may also occur during participant component add/remove, but is harder to reproduce.

This can occur on GNU/Linux as well.

I believe I have a solution. It's strange, as it seems the registered QVideoSink objects are sometimes demoted to QObjects just prior to the destruction of their parenting VideoOutput component. The workaround is to connect a blocking callback to QVideoSink::destroyed to unregister before calling QVideoSink::setVideoFrame on a QObject.
