Disable TFA Confirmation Email Fails

Problem/Motivation

When disabling TFA with Google Authentication enabled, an error message appears saying

Error sending e-mail (from [admin@example.org] to [admin@example.org]).

and

Error sending e-mail from [admin@example.org] to [admin@example.org] : Message body empty

I also have the SMTP module and Mail System module enabled but the issue seems to be that the message body can't be found since its function has been titled with a different hook.

Proposed resolution

Change hook to reference function correctly

Remaining tasks

Code the change (one line)

User interface changes

None

API changes

None
