    libtracker-miner: Pass parent to _insert_store_info()
    
    As both places doing this iterate directories one by one, we
    can optimize GFile interning by providing an already interned
    common parent.
    
    This eases the GNode lookups in TrackerFileSystem, as we already
    know the most direct parent GNode the file should have.
