    libtracker-miner: Check for NULL before unrefing sparql in item_update...
    
    Also, make warning about stat error into a normal message, this is
    perfectly normal if we add a file to the queue to be processed then it
    has been removed by the time we get to add it to the database, it is
    not a problem.
