Update jest monorepo (major) (#2407)

* Update jest monorepo

* -w

* Fix guest rooms test to use async/await instead of a done callback

The done callback was never being called because it relies on a `process.nextTick()` deep within the mock. For this test we don't get a "next tick" because the event loop is busy, so we instead cargocult some test infrastructure from surrounding tests and verify the expected API call was cleared from the queue.

* Enable github-actions reporter

* Don't override local reporters

* Stop DeviceLists at end of tests

* stop more clients

* Fix tests and DRY typing

* Fix client/crypto stopping in tests

* Fix Buffer c'tor deprecated warnings

* Fix devicelist-integ test being excluded due to poor naming
