Depending on timing, the first `httpBackend.flush()` could end up just flushing
a '/presence' call rather than the initial sync. The fix to that is simply to
not set the expectation on /presence.
While we're there, split out the flushes of /publicRooms and
/thirdparty/protocols, so that we can be sure that they happen.
There is probably still a bunch of flakiness there, but this should fix one
particular instance.
This test assumed that `/sync` would be called immediately after rendering
`<MatrixChat />` but this isn't true in an IndexedDB world: it bounces via
`store.startup()` first.
It looks like the tests resolve this by adding `q.delay(1)` so that's what
I've done: in the future it would be better to extend `HttpBackend` to have
a `waitFor(req) Promise` function so we can removing timing from the tests.
* Make sure we only get one js-sdk (and update runtime config to match)
* Don't verifyNoOutstandingRequests (since it is hard to be certain which we
will get, and makes the tests too dependent on implementation-specifics).
* Disable color for npm test, to avoid confusing Jenkins
