Make Special:IndexPages not show invalid page ids

Special:IndexPages outputs a blank line for anything that's not
a valid title. The query figures out page name and namespace by
outer joining on page. Given that all entries missing page_title
are going to be a blank line anyways, use an inner join instead
of an outer join.
