[FIX] hr_recruitment: add company_id to the context

Steps to reproduce:
-------------------
- go to Recruitment app and click on a job position;
- for an application without recruiter,
    click on the "Assign" button on the kanban box.

Issue:
------
A traceback occurs.

Cause:
------
To find available user_ids,
we use the `"[..., ('company_ids', 'in', company_id)]"` domain.
But `company_id` is not in the context.

Solution:
---------
Add `company_id` in the context by adding it to the view.
