Fix order of method execution in Fabric ViewManager

Summary:
Because of the changes made in Fabric, the order of the execution of some methods in ViewManager has changed. In Paper the following order was guaranteed: `createViewInstance -> addEventEmitters -> updateProperties -> onAfterUpdateTransaction`. But in Fabric, the order is the following: `createViewInstance -> updateProperties -> onAfterUpdateTransaction -> addEventEmitters`. This change can actually break some existing view managers, because they rely on the fact that `addEventEmitters` will be called before `onAfterUpdateTransaction`. Check ReactVideoManager:

```
ReactModule(name = ReactVideoManager.REACT_CLASS)
public class ReactVideoManager extends SimpleViewManager<ReactVideoPlayer>
    implements VideoManagerInterface<ReactVideoPlayer> {
...

  Override
  protected void onAfterUpdateTransaction(ReactVideoPlayer view) {
    super.onAfterUpdateTransaction(view);
    view.commitChanges();
  }

 Override
  protected void addEventEmitters(
      final ThemedReactContext reactContext, final ReactVideoPlayer view) {
    view.setStateChangedListener(
        new ReactVideoPlayer.PlayerStateChangedListener() {
...
}
```

As you can see there is a state change listener registered in `addEventEmitters` and `view.commitChanges()` can actually cause a state change. It means that if `onAfterUpdateTransaction` is executed before `addEventEmitters`, the state change listener will be added after a state change has happened and the event will be missed.
