Subject: [PATCH] fix NativeAnimated event listener bug
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
This bugfix cleans up reference to value listener upon unsubscribing to native events ultimately preventing RCTEventEmitter from throwing a [listener count error](https://github.com/facebook/react-native/blob/v0.33.0-rc.0/React/Modules/RCTEventEmitter.m#L90):

`Attempted to remove more RCTNativeAnimatedModule listeners than added`
