TextInput - `selection` prop is not set on component creation

[alanleedev]

Summary: Problem: selection prop is not being set on component creation. Not quite sure which RN version this issue was introduced but fixing it on latest code.

Use playground for testing (refer to following diff)

Proposed Solution:

Added notes in comments but viewCommands.setTextAndSelection() is called only on text or selection update which relies on comparing data with lastNativeSelection. Problem is that lastNativeSelection is initially set to the props value that is passed in so does not send the command on component creation.

So assign a default selection value of {start: -1, end: -1} so it can be set on component creation.

Changelog: [General][Fixed] - 'selectionprop inTextInput` was not being applied at component creation
