update jest, refactored some test config as a result, had some broken tests with the timeout dialog which were hard to unpick/isolate with jsdom so I've refactored a lot of them into the browser-based tests instead, seems like we don't need --runInBand (run tests in sequence) so they should run faster now, but we'll see if that holds up in jenkins.
[x] I think I've still got a bit of tidying up to do before this is totally ready for review.
most of this is moving around test coverage and trying to simplify test code so it's easier to maintain in future 🤞
