There was a bug with stroke where if I sent a large amount of messgaes (cica 1000) and then disconnected, not all the messages would be sent before storke handled the disconnect. It seems it did not fully lear the write buffer before closing the stream. This patch shoudl fix the error. It now only closses if the disconnecting flag is closed and the write buffer is closed. This should bring it into line with Swiften behaviour. Test-information: I had a simple stroke application that sent 1000 messages and then disconnected. Before the patch it would only send abut 80 or so of the messages before it got disconnected. After the patch it now sends all the messages before disconnecting.
