Log a socket error once, from WsServer

WsServer.handleConnection now listens for errors on every socket for its
whole life, and every socket a WsServerConnector holds comes from there,
new sessions and resumed ones alike. The connector's own listener only
logged the same error a second time, so it is removed.
