Bug 40602: Broken HTML showing in Alert 'subscriptions' tab

This patch adds handling of the "no-html" flag to patron-title.inc. The
OPAC alert subscriptions page passes the "no-html" flag but the include
file wasn't written to include it.

To test, apply the patch and log in to the OPAC as a user who has a
title (salutation).

- Add a serial subscription and set a notification template
- Go to the OPAC and subscribe to the email notification for this
  subscription
- Go to the patron account > Alert subscriptions tab
- Verify that the last column shows an "Unsubscribe from email alerts"
  button.
- There should be no errant HTML.
