Fix iOS e2e tests: bump react-native-babel-preset to ^5 (#19625)

Summary:
We opt in to version ^5 of the React Native Babel Preset, as required after the bump to Babel 7. This fixes the Objective-C end-to-end test failure in master. (Fixes #19538)

See 34bd776af2 (commitcomment-29024085) for prior discussion.

There have already been several changes made to the repo during the transition to Babel 7. This PR brings all tests back to green and allows us to move forward with the 0.56 branch cut.

We also bump our tests to use Xcode 9.4.0 and iOS 11.4, the latest stable versions of both.

Once the 0.56 branch makes it to stable, we can change `react-native-babel-preset@latest` on npm to point to `react-native-babel-preset@5.0.1` (or newer), and undo the change made to `init.js` we made as part of this diff.
