vo_opengl_cb: clear last video frame on uninit()

Browse Source 
mpv_opengl_cb_render() is supposed to clear the screen with the
background color if there's no video... I think.

It didn't do this, because although uninit() requested gl_video_config()
to be called, this didn't happen, because this function checks whether
the VO is set - and it's unsert after uninit() releases the lock.

Also call the user wakeup callback in this situation, so the user
actually redraws immediately.
