fix: await handlePullRequest in rerunCheck and correct asyncs in tests

- test 'check_run rerequested' added to test it
- test methods that should be async made async
- commentOnPull made true to also test the appropriate code path
- handlePullRequest in tests replaced with handlePullRequestWithRally to escape creating real rally instance, that runs its own asyncs, that are left after the tesrts are over
- setup.js with fail on unhandledRejection added to catch async warnings like the one appeared with the absent Connections._ref in rallyClient
