Florian Schmaus 525ee09ea1 [tcp] Do not send SM ack after we send a </stream:stream>
Do net put an ack to the queue if it has already been shutdown. Some
servers, like ejabberd, like to request an ack even after we have send
a stream close (and hance the queue was shutdown). If we would not
check here, then the ack would dangle around in the queue, and be send
on the next re-connection attempt even before the stream open.

See the following trace of the MUC bookmarks integration test. The
fact that it is a MUC test does not matter, but this test does
disconnect the connection and reconnect it. Not how the server,
ejabberd in this case, requests an SM ack by sending an <r/> even
though we already send the </stream:stream>:
