    tracker: Eliminate duplicate search results
    
    Add a DISTINCT to the query to eliminate duplicate search results when
    using grl_source_browse() on a grl-tracker source. Unlike other uses of
    DISTINCT in the source, it is not conditional on the browse-filesystem
    config key being enabled.
