    libtracker-miner: Preserve first cached event
    
    We cache both CREATED and CHANGED events here, if we get both while
    waiting for the CHANGES_DONE_HINT, it makes things more consistent
    to cache the first CREATED event.
    
    This did not result in bugs as the miner reacts the same either way.
