Do not remove last line with stats when connection is terminated because...

... of no response from ncsvc.

Example:

alex@debian:~/jvpn$ ./jvpn.pl 
Enter PIN+password: *********
Transfer went ok
Got DSID

BTW, for ncui version everything is OK with stats on connection lost, the \r is printed just before stats refresh, as in this PR.

P.S. thank you for a great script!
