    Unset correctly GVFS file attributes
    
    remove_attribute() removes the attribute from the FileInfo, so when
    calling g_file_set_attributes_from_info(), the attribute value is kept
    as-is, it was not unset.
    
    To unset the file attribute, we must set the attribute to an invalid
    type (it seems there is no nicer way to do it).
