Stabilized TestIdTestApp integration test

Summary:
- TestIdTestModule instrumentation tests is responsible for too many occasional crashes, e.g. https://circleci.com/gh/facebook/react-native/7054.
This should fix the problem (will monitor over next week)

- Made file naming more consistent

- 5 retries don't make e2e tests more stable, reduced back to 3 but I need to investigate how to make it more reliable
Closes https://github.com/facebook/react-native/pull/7784
