[FIX] inter_company_rules: purchase order with company fiscal position

The `fiscal_position` in the values dict for the `create`
expects an id, not a browse record.

This prevented to automatically create purchase order
from a sale order in an inter company environment
when the fiscal position of the companies were set.
