[gtk+/wip/cssnode3] searchenginetracker: Unify fts/non-fts query

[Matthias Clasen <matthiasc src gnome org>]

    searchenginetracker: Unify fts/non-fts query
    
    This makes sure we use location_uri for both types of query, and the fts
    query has been made more similar to the one used by nautilus.
