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
