Closing TCP connection in think state considered an error?

I noticed the following error messages in tsung nodes logs:

=INFO REPORT==== 13-May-2015::11:53:55 ===
           ts_client:(3:<0.7014.0>) Error: Unknown msg {tcp_closed,
                                                        #Port<0.133649>} receive in state think, stop

While I do think that this might be interesting when debugging things, I think we should properly handle this and only report this on log level debug.

There's a specific clause for tcp_closed, but it does not match this one (no Data in message); i will handle this one also.

Nice, thanks!
