[gnome-control-center/wip/carlosg/search-tracker3] search: Check for either tracker 2.x or 3.x schemas




commit 3a04116d6d16708b91f284ea40fc78b878b5d26e

    search: Check for either tracker 2.x or 3.x schemas
    
    The Tracker3 schema points to the same dconf path and is backwards
    compatible with Tracker 2.x settings. Check for either here, with a
    preference to Tracker 3.x.
    
    Eventually, Tracker 2.x will be fully phased out, and this will not
    be necessary.
