Bug 22139: Fields of ACCTDETAILS email not populating

To test:
* Make sure AutoEmailOpacUser is set to "send"
* Create a new patron with a username and password, and an email address
* In Kohadevbox, check the mail (usually you can type "mail" and go down
to the last message) - these do not go into the message queue and they
are processed immediately.
notice that the email does not have
<<borrowers.title>> <<borrowers.firstname>> <<borrowers.surname>>

Apply this patch, restart the things, retest as above.
