[grilo-plugins/wip/carlosg/tracker3: 10/11] tests: Add tests for the tracker3 plugin

commit be070086bcfc7fa7fb384b2af5158f90e7764156
Author: Carlos Garnacho <carlosg gnome org>
Date:   Sun Jun 28 17:19:35 2020 +0200

    tests: Add tests for the tracker3 plugin
    
    Use the tracker 3.0 testutils helpers to run a tracker sandbox, and put
    some sample files on it (borrowed from chromaprint and tracker-miners
    tests) so we can test features in the grilo plugin.
