[Blink] wrong request uri

[Juha Heinanen]

i added ;transport=tcp to outbound_proxy and as result blink
constructed this kind of request uri when i called 4444 at sip2sip.info:

INVITE sip:4444 at sip2sip.info;transport=tcp

it is plain wrong.  blink should not mess around with whatever user
writes as request uri.  if outbound_proxy has a particular transport
protocol, blink should use that to reach outbound proxy and leave
request uri as is.  now i cannot call sip:4444 at sip2sipinfo at all
because that domain does not support tcp.
