Use safeClose() in ClientServiceHandle.close()

      When shutting down the server, this exception gets raised: 

      11:33:04,028 INFO  [org.jboss.as.server] (Thread-2) WFLYSRV0220: Server shutdown has been requested via an OS signal

      The ClientServiceHandle.close() method needs to use safeClose() in case the channel variable has not been initialized, which can happen if the service creation is cancelled or raises an exception.
