Comment:

 Ok, I committed a change with the loadGroup fix as well as a hack to use
 the referer host if we have neither loadGroup nor notificationCallbacks..

 It solves all of the test cases above, but I'm not sure if the referer
 property is present in the channel for http->https sourcing.. Any test
 cases of that? If we get lucky, it might be present but not transmitted.
 From reading
 https://developer.mozilla.org/en/XPCOM_Interface_Reference/nsIHttpChannel
 it sounds like we won't get lucky... But is there anything else we can do?
