Re: [PATCH v4 0/3] MR2496: Fix hang when a program calls IMFMediaSession_Start with an invalid source.

[Santino Mazza (＠tati1454)]

I've removed the wait_for_media_event from the ClearTopologies calls because it hangs the test in wine, because the MESessionTopologiesCleared event is received by the wait_for_media_event for MESessionStarted.
