* When setting company_id on the res.partner, the parent might have had
a different company_id
* We should not consume res.partner's when creating res.user's but
creating new ones instead.

ids.
The lunch.supplier population was crashing because no partner id was
present in the partner population registry to use as `partner_id` for
the generated lunch suppliers.
