[FIX] hr_recruitment: correct count in mutli-company context

Steps to reproduce:
-------------------
- create a job position without specifying the company;
- being in the first company, create an application for this job position;
- being in the second company, create an other application;
- go to the job position kanban view;

Issue:
------
Despite the selected company, the count for this job application is still two.

Solution:
---------
Include the allowed companies in the query to count the number of applicants.
