Update emails from certificate worker to match pattern of other emails

Since the certificate worker is sending a job to the mails worker just
like the controllers, it should prepare the email in the same way by
localizing and then sending the inner template for the mail worker to
apply the layout and final variables.

This commit also fixes a problem with a missing subject.
