Do not scroll to child inside nested scroll view (facebook#54044)

Summary:
Pull Request resolved: facebook#54044

In rare cases, there may be a vertical ScrollView nested inside another vertical ScrollView. In these cases, when the requestChildFocus method is called, we may attempt to bring the entire focused child into view. However, we really only want to bring the entire nested ScrollView into view.
