Use a single entry point to the app.

We are currently using identical `index.android.js` and `index.ios.js`
files.

I assumed we only need to replace both files with one `index.js` but
it turns out it is a bit more complicated.

Support for single entry-point was introduced and made default in
RN 0.49:
  https://github.com/facebook/react-native/releases/tag/v0.49.0
  facebook/react-native@6e99e314b

This PR:
 * uses only one of the two identical index files and names it `index.js`
 * changes configurations for Android and iOS to facilitate that
 * also updates AppDelegate.m with an older upstream cleanup:
   facebook/react-native@a9a0ff267  In fact this change doesn't seem
   to work without that cleanup, though it's unclear why.
 * updates our documentation about this (a minor tweak)
