#3818: Add buddy + Authorize buddy duplicate buddies

 This has happened to me with ICQ buddies

 Somebody added me to their contact list and asked for my authorization.

 Pidgin showed both a message box (see also ticket #3804 about this box)
 and a panel at the bottom of contact list both asking the same question -
 accept or deny?

 I clicked "accept" in the message box and added the buddy to the
 appropriate group.
 The panel, however, didn't go away. As I clicked "accept" again, I again
 had to add this same user to the list and I ended up with two identical
 buddies (deleted one of them, of course).

 Desired behaviour: when a buddy is added from one place, hide the other
 (if I accept from the message box, hide the pane and vice versa).
