Improve AztecWrapper RN TalkBack support. #918
Description
From #916 we noticed that TalkBack on Android will focus on RichText without the need of activating it (with double tap).
This is contrary to what the Accessibility documentation says on React-Native pages, and it's different to how TextInput behaves.
The behavior expected from the Screen Reader is to select the item, and focus on it when the user double taps.
It's much appreciated if an Android expert could investigate this issue and help us find a solution.
