Peter Argany fab5fffbb3 Fixed OSS scroll view bug caused by FBPullToRefresh
Summary:
When I bridged FBPullToRefresh to RN, the integration with ScrollView caused a bug on OSS

TLDR; assuming that a scrollview subview that implemented UIScrollViewDelegate protocol was a custom PTR was a bad idea. This caused some scrollviews to break in OSS. The solution is to define a more explicit protocol.
