Found this via a google search. It looks simple and looks like it does what you want but
I have not tested it.

Subject: [Mediawiki-l] Avoid duplicate listing of articles after renaming/moving?
I am using MediaWiki 1.12 version. Let's say I renamed/moved an article with
title "Project Blue" to it's new title "The Blue Project" using
sysop admin
account. Now if I go to the Special Page "Special:AllPages", I still see the
name "Project Blue" along with "The Blue Project". How can I make
mediawiki
NOT to display the old title (Project Blue)?
I know Mediawiki internally keeps a mapping/redirection when articles are
moved which is fine but I would like that when somebody clicks on
"Special:AllPages", the old title does not appear just to keep it clean and
less confusing.
Any ideas?
