* Define matchers to test promise fulfillment
These are useful for validating that promises depend on other events prior to fulfilling.
* Expose custom matchers to jest projects
Team-specific projects are not touched here to try and reduce review burden.
* Block browser local operations awaiting reseed
This should closes a narrow race condition resulting from storage operations during a reseed event.
* Import from barrel file
This might fix the failing test, but I'm not sure _why_
* Document helper methods
* Validate as few properties as possible per test
* Simplify expected value representation
* Allow waiting in promise matchers
* Specify resolution times in promise orchestration tests.
* Test behavior triggering multiple reseeds.
* Fix typo
* Avoid testing implementation details
* Clear reseed on startup
in case a previous process was aborted in the middle of a reseed.
* Correct formatting
