Fix Labels section in transmission-remote output.

[vchimishuk]

I noticed that transmission-remote output is broken, Labels section is not correct.
Current output:

$ ./transmission-remote -t 2 -i

With proposed fix:

$ ./transmission-remote -t 2 -i

Ouch. We need integrated tests for transmission-remote
