Fixes #926

Findings

The AztecText view was focusing on hover during accessibility mode.

Solution

The solution was to modify the AztecTextAccessibilityDelegate that was intercepting the MotionEvent on hover since that triggered the delegate's logic which involved requesting the focus on the AztecText view.

Testing

1. Open the example app.
2. Enable TalkBack by long-pressing both the volume up & down key at the same time.
3. Once it's enabled, hover over the example content of the AztecText view.
   I modified the string content from EXAMPLE to QUOTE so testing would be easier.

4. TalkBack should read out the entire content, but the view should not be focused until you double-tap it.
5. Before TalkBack would say long-press the control as the first option but now it says tap as seen below.
6. Ensure that tapping actually causes the cursor to become visible since the view is no longer going to be focused automatically.
