[tracker] libtracker-miner: Remove TrackerCrawler max_depth argument

[Carlos Garnacho <carlosg src gnome org>]

commit ef421db6c8938cd1a1a07727c31a4ef60caf45be

    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.
