…ebook#36648)

Summary:
Pull Request resolved: facebook#36648

Changelog: [Internal]

Blocker for facebook#36623. The `test-ios` job in CI was misconfigured following the monorepo migration — and this becomes load-bearing with the incoming version of React Native CLI.

- Update `objc-test.sh` to run in `packages/rn-tester`, and exclude tests under `/IntegrationTests` which are outside of a Metro project directory.
    - **This is temporary** — a task has been created to move/split up/otherwise restore tests in `IntegrationTests`, which cipolleschi is following up (thanks!).
- Also fix `yarn start` script in `packages/rn-tester`.
