[Serusers] rport processing bug

[Jakob Schlyter]

when my phone sends the following REGISTER (from port 2084) to ser 
(0.8.14-2), ser will rewrite the contact before storing it into the 
location databases and ends up with 
"sip:195.47.254.134:2084;transport=udp;line=q67m1xq1". this is bad since 
the phone is not listening on port 2084 at all and INVITEs will not work.

as I understand, the rport is only significant per transaction and should 
not be applied to further signaling with the peer (such as INVITEs).
