[FIX] sale, sale_product_configurator: Quantity not copied from Configurator to Rental Wizard

Steps to reproduce the bug:

- Let's consider a rental product RP with variants
- Configure product configurator
- Create a rental order
- Select RP and set a quantity in the product configurator
- Click on Add

Bug:

When the rental.wizard was opened, the quantity was not taken into account and was reset
to 1.
