[reSIProcate] r4478: missing OK for incoming INFO requests

[Dmitry Semyonov]

Hello.

Up-to-date DUM does not send OK in response to incoming INFO requests.

It seems
  mDialog.send(mLastNitResponse);
should be added somewhere after 
  mDialog.makeResponse(mLastNitResponse, msg, 200);
inside dum/InviteSession.cxx:InviteSession::dispatchInfo().
