Extend swigged TestServer to expose port and sync xmpp port to python

To be used with pyauto.
Usage:
    sync_server = pyauto.TestServer(pyauto.TestServer.TYPE_SYNC,
                                    pyauto.FilePath(self.DataDir()))
    sync_server.Start()
    print sync_server.GetPort(), sync_server.GetSyncXmppPort()
    sync_server.Stop()
