This is the same race as #1495 but in sendStreamResponse rather than sendError.

This commit tries to deflake failures reported in https://ci.appveyor.com/project/garrettjonesgoogle/google-cloud-java/build/57 .
The failure seems to come from
FakeSubscriberServiceImpl::sendError. When callinggetAndAdvanceCurrentStream, we waited for there to be a subscription by waiting on thesubscriptionInitializedvariable.The variable is notified before
addOpenedStreamis called though, and so it's possible thatgetAndAdvanceCurrentStreamwill see a list without any opened stream. The fix is to wait for at least one stream to be registered first.@davidtorres Another option seems to be moving
addOpenedStreaminto the synchronized block. I'm not sure which is the better option.
