* MatrixChat-test: clean up better in `afterEach`
Make the MatrixChat tests behave better by letting them finish their work in an
`act` in afterEach. Otherwise we can end up mounting new components during
cleanup, which run tasks in the background
* MatrixChat-test: clean up dispatcher test
This test was kicking off a dispatcher job which would then open a
UserDeviceSettings dialog once the test had finished. That would then throw
exceptions because some of the mock environment had been torn down.
We're just testing that it opens the right dialog, so better to intercept
`createDialog`.
Aso add an `act` to reduce warnings, and replace a `flushPromises` with a
`waitFor` to make the test more robust.
Any UTs for vector-web layer components or functionality should go here.
This used to contain the UTs for notifications before they got moved to react-sdk.
