LP#1197636 - Email record detail does not check for email

Even though no email was configured, the message shown when requesting bib information to be emailed
indicated success.  This misleading behavior has been addressed by alerting the patron of the situation
and providing a link to the page where the email address is defined, after which the action is automatically
retried.

The success message has also been altered slightly to provide confirmation of the generated email.
