[FIX] purchase: description of a product

When a move is creating from a purchase order line and the destination
of the order("location_id") is "customer", the description of the created
move must be the name of the product. To avoid that the supplier description
of the product appears on the customer invoice because in "drop shipping",
the customer invoice line is created with this created move by the function
"_get_invoice_line_vals".
