MetaWindowActor: don't overwrite send_frame_messages_timer

Browse source 
If the app finished multiple frames before we sent _NET_WM_FRAME_DRAWN,
we could add the send_frame_messages_timer multiple times. In the rare
case that the app immediately closed the window, the older timeout
could potentially then run on the freed actor.
