    libtracker-miner: Unset parent folder iri cache if dealing with the root dir
    
    This fixes infinite recursion when indexing an out-of-config-trees file
    (eg. via tracker-control -f <file>), as the miner aditionally indexes the
    parent folders up to file:///, when reaching that case stale URN cache data
    was making the miner think that the root folder hadn't been indexed yet.
