Fix interactions with NativeViewGestureHandler (software-mansion#1034)

### Context
[`transformIntoHandlerTags`](https://github.com/software-mansion/react-native-gesture-handler/blob/master/createHandler.js#L91) creates an array of valid refs based on the value of the property `_handlerTag` of each ref passed to `waitFor` or `simultaneousHandlers` prop. The filtered array is then sent to native for configuration.
### `NativeViewGestureHandler` 
In the case of `NativeViewGestureHandler` the `_handlerTag` is set on the `NativeViewGestureHandler` ref properly.
**HOWEVER**, this value isn't passed to the ref of it's child. The child's ref is the one being passed back as the ref handler of the component. This makes sense.
**However**, in order to configure interactions on a different handler one would need to pass the `NativeViewGestureHandler` ref as part of `waitFor` or `simultaneousHandlers` prop. 
This is **IMPOSSIBLE** because the `NativeViewGestureHandler` ref isn't exposed.
The child's ref is passed instead and is filtered out by `transformIntoHandlerTags` due to the lack of `_handlerTag` property, making it completely useless.
### The End
This PR fixes the mentioned problem by setting the `_handlerTag` property on the `NativeViewGestureHandler` **child's ref** so when it is passed to `waitFor` or `simultaneousHandlers` it is treated as if it were a genuine gesture handler.
