Fix LayerTreeHostCacheBehaviorOnOutputSurfaceRecreated test

LayerTreeHostCacheBehaviorOnOutputSurfaceRecreated test was incorrectly
relying on WillBeginImplFrameOnThread only being called once after the
OutputSurface was recreated. In reality, this function could be called
multiple times.

This patch causes us to handle cleanup in DidInitializeOutputSurface,
which will only be called once after recreating an OutputSurface.
