commit 78b1c1dcfb5e369c685a92ae0d286d789f317bfb
Author: Carlos Garnacho <carlosg gnome org>
Date:   Sun Nov 21 16:03:37 2021 +0100

    libtracker-data: Provide graph information at describe queries
    
    And ensure ordering by first subject then graph, so information for a
    single resource from multiple graphs is clustered together. Since
    the cursor format and output changed, update the tests that expect a
    specific DESCRIBE output.
