Steps to reproduce the bug:
- Install purchase, then mrp (in this order)
- Create a storable product “P1”
- route: buy
- Add a supplier
- Add a BoM
- Create a delivery for the product “P1”
- A need is created
- Go to inventory > operation > replenishment
Problem:
An orderpoint is created with the preferred route: Manufacture instead
of buy
As the "Purchase" module was installed first, the override of
the `_set_default_route_id` function will be triggered first, the 'buy'
route will be set in the created order point because the product has a
supplier. Then, the function in the MRP module will be triggered and
since the product has a BoM, the 'buy' route will be replaced by
"Manufacture".
