[FIX] sale_stock: Unable to set default warehouse when creating a quotation

Steps to reproduce the bug:

- Go to inventory > settings > enable multiple warehouses
- Let's consider the default warehouse W
- Create a new warehouses NW
- Enable debug mode
- Go to sales > create a new quotation
- Go to the other information tab > change default warehouse W to the newly created warehouse NW
- Click on the bug > go to set defaults > warehouse=NW > save default
- Refresh the page > Go to sales > create a new quotation
- Go to other information tab > observe the warehouse

Bug:

The warehouse was W instead of NW
