[FIX] hr_recruitment: Fix traceback on applicant quick create

Currently, when got to applicant view and quick create the applicant
in the kanban view there is traceback for department_id.
becasue department_id is computed field which depends on job_id
and it was not set as False due to filter on self.

So in this commit, If job_id is not there then department_id
should be set as False.
