Partially fix that beginning of animation is skipped

When waiting for all the windows that belong to an activity, we
skipped the main window, in case it didn't had a surface yet. This
was a problem because with SurfaceViews: They set it's visibility
extremely early in the app visibility change cycle. Then, they don't
block with the callback to SurfaceHolder.Callback2.surfaceRedrawNeeded,
so window manager thinks it has drawn the first frame already. We don't
even have a surface for the main window yet, but we start the app
transition already because we think the only interesting window for this
app token is the SurfaceView, which has supposedly already drawn.
