[gnome-games/wip/jfelder/tracker3-port: 2/3] Port to tracker3

[Jean Felder <jfelder src gnome org>]

commit 531c072a4e2eac1faf54c70c681da2abfe16edcb
Author: Jean Felder <jean felder gmail com>
Date:   Sat May 30 18:48:06 2020 +0200

    Port to tracker3
    
    With tracker3, tracker-miner-fs dumps data in different graphs. Games
    only needs to access data stored in the tracker:Software graph.
    
    'tracker_sparql_connection_get' has been replaced by
    'tracker_sparql_connection_bus_new'.
