[FIX] stock_picking_delivery_link: Resilient test

Avoid the error:

```
odoo.exceptions.UserError: There is no matching vendor price to generate
the purchase order for product Test Product (no vendor defined, minimum
quantity not reached, dates not valid, ...). Go on the product form and
complete the list of vendors.
```

when `purchase_stock` module is installed. This is because the "Buy"
route is activated then by default. Putting no routes is not valid
either, as we receive then the error:

```
odoo.exceptions.UserError: No rule has been found to replenish "Test Product" in "WH/Stock/Shelf 2"."
```

so the solution is to force the warehouse route to procure.
