[FIX] stock: fix creation of picking type for a other company

In multi company (company A and B),
- Select the company A as main one, and select B too.
- Create a picking type and change the company to B.
- Don't select any warehouse.
- We can't save, because the company ir.sequence is
set to A instead of B.

Fix by apply the company_id of the picking type.
