Use the same branch tag in CANCEL as in INVITE

Originally putnopvut implemented some changes in revision 142079 that according to the bug report seemed to have worked then, but somehow fails now.
I guess code, as humans, get old and forget stuff. Anyway, this bug caused CANCEL not to work with picky systems.

Thanks Fredrik for pointing out where the bug in the SIP messaging was.
