[BUGFIX] Only show default language pages for sorting

The sorting of subpages also shows all translations
which leads to very bad side-effects due to the removal
of pages_language_overlay. This case wasn't fixed yet.

The query for fetching all subpages is now adapted to
only fetch pages with sys_language_uid=0.
