gs-age-rating-context-dialog: Clear attribute and row state with widgets
When clearing the widget state, also clear the internal lists of
attributes and rows, otherwise self->rows
continues to point to freed
widgets (which were in self->attributes_list
), and self->attributes
continues to cause add_attribute_row()
to think the row widgets still
exist.
