    tracker-miner-fs: Reset retry counter when we need to prepend parents
    
    The situation where a parent directory has to be prepended in order to
    process the current file is rare, mainly reserved to IndexFile calls
    on files out of watched dirs.
    
    This is a corner situation, but it is a legit place where we have to
    put the file back again in the queue, and thus we shouldn't increase
    the retry counter.
    
    This nominally fixes the indexing of gnome-documents-getting-started.pdf
    on a fresh-out tracker DB, as requested by gnome-shell.
