Subject: [PATCH] Correctly find rootView when RCTTouchHandler is in a
 RCTSurface

Summary:
@public
I'm surprised this hasn't caused an issue earlier.
RCTTouchHandler is hooked up to RCTSurfaceView which itself contains a rootView. Thus when this calculation happens, a root view is never found.
We can't assign to the root view since it created and destroyed frequently, so it makes the most sense to look for the RCTSurfaceView here and treat it as a root view.
