    base-manager: Do not replace existing objects for a particular ID
    
    This will let us re-use the PhotosItemManager for the Favorites mode,
    where we will look for items marked as favorite. Otherwise we would
    end up emitting an extra "object-added" for an object that belongs to
    both modes.
