[FIX] fix multi-company test

Record rules used to not be checked on stock quants, but now they are since Odoo's commit 2fd14db57433d08ab368a7e18d18ae8d49dafab1 (https://github.com/odoo/odoo/commit/2fd14db).
In our test we changed the company of the products and BoMs but we neglected that the stock was not attached to the right company, and that made the test fail.
To fix that, make the test inventory for the right company.
Since there is a little inconsistency in the demo data with a negative quantity of an unrelated product, use the `partial` filter for the inventories instead of the `none` filter, so that no wrong inventory lines are added automatically.
