[FIX] mrp: inventory value of produced items
[FIX] mrp: inventory value of produced items

Since the revision bc23c92c3ed07283bbd40f88ce73024572922a72,
the inventory value of the produced items could
be doubled, because the list
`total_consume_moves` could contain several time
the same move ids, e.g. when it was added by
`total_consume_moves.append(raw_material_line.id)`
and
`total_consume_moves += already_consumed_lines.ids`

The list is replaced by a set to ensure a same move
cannot be counted twice.
