[grilo-plugins/wip/trackernotifier: 17/18] tracker: Remove per-device-source configuration



commit 943685048d37aa5a78e902d44c07450e5706c732

    tracker: Remove per-device-source configuration
    
    This is not entirely right, and could yield errors similar to commit
    73c1aa1e7, where events go undetected because the deletion time of
    properties is not guaranteed to be atomic, so there might be missed
    events where files no longer qualify for certain notifications.
    
    Given this is a configuration toggle meant for plugins/integrators,
    it seems we can do without it.
    
    Closes: #14
