Fixed: on the server side RMIComm.Facade#connected() was not called

As a result, the disconnect() counterpart was always ignored, which
prevented a client that has been previously brutally disconnected (no
notifiction to the server) to be unable to reconnect anymore, until
the server was restarted!
