Fix a problem where the Asterisk channel name could be that of the wrong IAX2
user for a call.  This is because the first step of choosing this name is to
look for an IAX2 peer that happens to have the same IP/port number that this
call is coming from and assuming that is it.  However, this is not always
correct.  So, I have made it change this name after authentication happens
since at that point, we have an exact match.
