[6.1][7.0][trunk][sale] Recreate Packing create duplicates

The "Recreate Packing" that is used to fix a sale order exception is actually recreating ALL procurements without checking existing ones. That leads to have for the same line multiple/duplicates :
- Picking
- Moves
- Purchase orders
- Production orders

A proper way would be to check for each sale order line the procurement status and recreate a procurement ONLY if the existing one is canceled.

If it's the case, then a new picking is created and attached to current sale order with the new procurements and matching lines watch their state reset to 'confirmed'. (Existing moves related to the previous procurement in these lines are canceled).
