[ListView] Fix RCTScrollView stickyHeader touch passing.

Browse Source 
Summary:
Point must be converted to the stickyHeader's coordinate space and then passed to the stickyHeaders hitTest:withEvent: method in order to be correctly routed to any subviews of the stickyHeader.

This resolves this [issue](https://github.com/facebook/react-native/issues/2075).
Closes https://github.com/facebook/react-native/pull/2224
