[FIX] purchase/sale_product_matrix: fix sequence of order lines

- Install Sales and Sale Matrix
- Go to Sales > Configuration > Settings and activate "Variant Grid Entry"
- Go to Products and edit a product with variants (lets call it "Product A"):
  * For "Sales Variant Selection" in "Variants tab", choose "Order Grid Entry"
- Go to Sales > Orders > Quotations and create a quotation
  * Add any product without Variant Selection set to "Order Grid Entry"
  * Add "Product A" with 1 attribute
  * Add any product without Variant Selection set to "Order Grid Entry"
- Here there are 3 products in the quotation with "Product A" at the second position
- Save the quotation
After the save the position of "Product A" is moved to the last position.

In a new quotation, every new order line has a sequence set to 10, except for products
with Variant Selection set to "Order Grid Entry" that set the sequence to the previous one +1,
which will put it in the last position even if another product is added after it.

[All of the above steps and explanations can also be applied to Purchase]
