[Port of firebase/firebase-js-sdk#1133] 1. Changed MAX_WATCH_STREAM_FAILURES to 1 per conversation with @wilhuff and @jdimond. 2. Fixed a "race" where when a get() triggered a watch stream error, we'd restart the stream, then get() would remove its listener, and so we had no listener left once the watch stream was "opened". Without a listen to send we'd be stuck in Offline state (even though we should be Unknown whenever we have no listens to send), resulting in the next get() returning data from cache without even attempting to reach the backend.

@wilhuff You have already reviewed this. I just moved it to this repo via "git diff" and "patch". Sorry for the extra churn.
