Handle possible null exception on ReactEditText with AppCompat 1.4.0 (#33769)

Summary:
This Change fixes a possible null exception as the user uses AppCompat 1.4.0
as a dependency in their App and uses a `TextInput` component.

The exception may happen as `mFabricViewStateManager` is accessed during
the constructor of the superclass, and is not yet initialized.
- For reference, commit #e21f8ec34984551f87a306672160cc88e67e4793 fixes the crash which was already happening.
