winegstreamer: Check the callback list before waiting. 

Some callbacks may be pushed during pipeline initialization and before
the dispatch thread is actually started and waiting for them, which
sometimes causes some hangs.

This fixes Fallout 3 and Panzer Corps -and possibly others- intro videos
hanging forever.
