Yeah I was checking the coverage bottom-up to make sure that all of the code 
paths in ClientRequestState/Coordinator were covered. Those two additional code 
paths go through UnregisterQuery(), same as the Close() path (and a bunch of 
other things).

It's not a bad idea to cover the other cases, but I think that would require 
switching the test to HS2, since beeswax doesn't have the same idea of sessions.

I guess we could drop the beeswax connection and check the state of the query 
via the debug server or similar, but then it would probably just make more 
sense to switch to HS2. I can have a crack at that but no idea how easy or hard 
that would be.
