[tracker-miners/wip/carlosg/shuffle-libtracker-miner: 13/115] libtracker-miner: Remove TrackerCrawler max_depth argument



commit 758939a009177ca69106f1d911cacb4e971feed7
Author: Carlos Garnacho <carlosg gnome org>
Date:   Tue Sep 26 16:06:45 2017 +0200

    libtracker-miner: Remove TrackerCrawler max_depth argument
    
    It was always called with depth=1 (return just direct children of the
    given folder), so make this the default. Admittedly, the "crawler" name
    is a bit of an stretch now.
    
    The TrackerCrawler tests have also been removed the recursive tests,
    since that's not possible anymore.
