bug#44439: url-http-handle-authentication: false positive "Wrong authorization used for"

[William Xu]

When I use excorporate elpa package to get outlook calendar into
orgMode, M-x excorporate, putting user and password info, I get this
error:

(defun url-http-handle-authentication (proxy)
      ... 
      (error "Wrong authorization used for %s" url))

even though I provided the correct password. In fact, if I change
`error' to `message', everything just works. All calendar events can be
downloaded successfully. 

I noticed the change has been added when resolving this ticket:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27022

Should the `assoc' check be refined a bit here?
