[Action] Fix action=ajax

* Move Ajax stuff to before regular title/page action handling. Ajax actions circumvent most stuff and return early from the regular execution.
* Needed because getAction / Action-classes can't handle action=ajax properly, which isn't until MediaWiki::performAction
* Also undo's debug 'true' in the if-statement from r109688
