[FIX] base: superuser on company creation

When creating a new company, SUPERUSER_ID is not added in `user_ids`.
Therefore, when installing a new module, the newly created company
is not in `self.env.companies`, which leads to an issue when
computing `company_id`.

Steps:

- Install Accounting module
- Create a new company with any localisation
- Delete the tax closing entry
- Try to install `stock_account` module
-> Error: `_check_company` failed

With this commit we add the company newly created to
the superuser's `company_ids`
