[FIX] hr_recruitment, receive email for applicant creation in right company

Before this commit, the email aliases on hr.jobs did not take into
account the department.
Hence, when receiving an email for an applicant through an alias,
the object applicant was created in the wrong company

after this commit, the alias is created with the right values, and the
applicant is created in the right company and department
