[IMP] mrp, stock: default route on orderpoints

Set a default route on orderpoint created by the replenishment report.
First it select the first route on the product if it exists (it's
uselss since it's a preferred route on the report but it's used for
clarity). If the product has no route then it tries to guess it
with vendor pricelist or BoM on the product.
