Summary: Unusual To: header formatting causes an NTA mismatch

Initial Comment:
The Codenomicon test suite in the proxy mode sends our UA a 200 OK response to 
REGISTER. In this case the response is not corrupted as usual for Codenomicon, 
only the To: header field misses space between the header name and the value. 
This apparently causes NTA to fail in matching the response to the REGISTER 
transaction:
