This seeks to fix the intermittent failure of the "MatrixClient rehydrated from
stored credentials" tests.
The problem appears to be that the 'load_completed' is sometimes taking a while
to come through from the dispatcher - or rather, it is taking a long time to
get *sent* to the dispatcher: the chain of `q().then().catch().done()` in
componentDidMount can take a while to happen.
As a workaround, give the test a few goes when waiting for us to start
syncing. It's not ideal to be poking into the internal state of MatrixChat like
this, but it'll do for now.
Promises are now not being resolved within the same tick, so give
another tick for the UI to update after all the HTTP calls have
flushed through. This is fairly terrible, but I can't immediately
see a better way of doing this.
The 'loading' tests only worked when run with the other tests and
failed if you just ran the file by itself, because the skin was
loading in the 'joining' tests, but not here.
1. fix the 'Clean load' tests which had been broken by
https://github.com/matrix-org/matrix-react-sdk/pull/399: make sure we clear
localStorage between tests.
2. Test the session rehydration properly by setting the localStorage rather
than setting up the MatrixClientPeg before loading the app.
3. Add some tests for the auto-guest-registration flows.
