Title: Addresses issue #1155 for the forever transports.

While PersistentConnection.OnConnectedAsync is running we queue all writes
to the response stream to prevent clients from prematurely indicating the
connection has started.

We keep the subscriber's receive loop running to allow the subscriber to
continue processing commands and to prevent deadlocks caused by waiting on
ACKs.
