* Fix pushing screens to external components inside modal

New class name is 54% shorter, thus better.

This commit fixes hiding the back button with `backButton.visible: false` in mergeOptions. It didn't work on Android.

Send componentType field in componentDidAppear and componentDidDisappear events.

The new field is either:
- TopBarButton
- TopBarTitle
- TopBarBackground
- Component

This works around a rare edge case where applying the translucent flag
resulted in white screens when pushing or showing modals.
So far, I've managed to reproduce this only when when showing external component as modal in the Wix app.
