Allow listener for native Animated.event 

Summary:
We used to not send events to JS when there was a native Animated.event but we do now so we can easily enable the listener property.

**Test plan**
Tested that the listener gets called when using native Animated.event.
Closes https://github.com/facebook/react-native/pull/12323
