[gnome-documents] tracker-controller: don't start automatically at construction

    tracker-controller: don't start automatically at construction
    
    Since we might be started in preview mode, avoid starting up
    immediately. The View object will fire it up when it's constructed
    (which is as soon as the WindowMode is OVERVIEW).
