#4868: Duplicate contacts created when multiple auth requests are received for the
same contact

 This happened to me while using jabber/xmpp, logged in to my google talk
 account.  A contact sent an authorization request to be added to my list,
 but I was not around to accept it, so he sent it 2 more times.  After
 accepting the request, the other 2 requests were still there, so one must
 either accept or reject (does reject cause them to be blocked?), so I
 accepted.  Then I had 3 entries from the same contact on my buddy list. To
 remove the extras, I had to edit the blist.xml file.

 Expected: multiple requests and adds from the same contact should result
 in only one copy of that buddy on the list.
