test: make crashOnUnhandleRejection opt-out
This commit removes `common.crashOnUnhandledRejection()` and adds
`common.disableCrashOnUnhandledRejection()`.

To reduce the risk of mistakes and make writing tests that involve
promises simpler, always install the unhandledRejection hook in tests
and provide a way to disable it for the rare cases where it's needed.
