[IMP] hr_recruitment: avoid sending stage change message to unarchived applicants

Purpose:
When the applicant is unarchived, they are automatically set back to
first stage. This is done automatically. In case there is automated
message post configured for that stage change, it will send the mail to
the applicant. We want to avoid this.

After this commit, the automated message related to the stage change
will not be posted in case the applicant has been just unarchived,
even if it is configured for the stage.
