Part of the problem in bug 70686 was that we were blindly redirecting special pages without knowing that the redirect target was another name for the same special page. Fixing that means we need to actually check the aliases' targets.

Fetching the aliases' targets means that the SpecialPage_initList hook may be called earlier in MediaWiki's initialization process. In particular, it may be called when determining the Title object to be placed in the RequestContext.
