[FIX] mrp: missing cast string to date

Usecase to repdroduce:
- Create a manufactured product with route manufacture and a RR
- Run the scheduler.

Orderpoint will prepare procurement values's date as string. Other
module could possibly also use string as date and a call to from_string
will not break anything if the value is already a date or a datetime.

closes odoo/odoo#38900
