[Bug] Registering a new user returns a 500 Server Error when Email Server is not set up

[morganlking]

Registering a new user from the login screen when I did not set up an email server generates and displays a 500 Server Error, but still creates the user.

Steps to reproduce the behavior:

1. Go to login screen and click on register new user
2. Fill out registration
3. You should be redirected to a 500 Error Page

I would expect it to automatically log you in or take you back to the login page and say email isn't set up

This is the intended behavoir. We could add some validation and check if the email server is set up.
