Cleanup for r27897:

* Title::getBaseText is misleading as this function returns the subpage of a subsubpage instead of the root page
  (maybe my fault by misinterpreting "Get the base name, i.e. the leftmost parts before the /"
* Fixes an issue for the (rare?) case that subpages are disabled for user (talk) namespace
