[FIX] sale, sale_prodcut_matrix: Default customer Lead Time not set with Order Grid Entry

Steps to reproduce the bug:

- Let's consider a product P with three variants red, yellow and blue
- Let's set a customer lead time on P = 10 days
- Set Order Grid Entry on P
- Create a quotation Q and add P
- In the grid entry matrix add 1 red, 1 yellow and 1 blue

Bug:

The customer lead time of these three variants were not set on the lines.
