    miners/fs: Correctly remove failed extractions from queue
    
    Correctly remove task from extraction queue if g_file_query_info_async()
    fails.
    
    This bug prevents failsafe extraction from starting in some cases, which
    in turn means that the miner may eventually stall due to the extraction
    queue being full.
