[tracker/wip/carlosg/update-perf: 16/61] libtracker-sparql: Pass TrackerProperty further in updates machinery




commit 20acbc742217934fda01402ef0d1e8f071e158cb

    libtracker-sparql: Pass TrackerProperty further in updates machinery
    
    We used to turn the TrackerProperty into table+column names before the
    operations got queued for execution. Pass the TrackerProperty all along so
    that we can use its other properties while flushing.
