Subject: [PATCH] Add flexibility to the iOS UIExplorer test script

Summary:
Add more flexibility to the iOS UIExplorer test scripts:
- support environments without `xcpretty` installed
- support custom xcode destination argument

Initial PR is based on the last git commit which passed on Travis today (2a92b52) in order to test Travis build.

I'll rebase to latest, in order to fix merge conflicts, before merging.

**Test plan (required)**

Make sure tests pass on Travis.
Closes https://github.com/facebook/react-native/pull/7982
