    libtracker-miner: if CREATED event is received from the monitor, force IRI cache update
    
     * The issue comes from NB#188494, but it doesn't fully fix it. The issue seems
       to be that the camera application is also inserting a new element in the store
       and doesn't check if it already exists before.
