Ghost User
2018-07-08T22:07:59+02:00

Invalid attempts at new users are already sent an email when one attempts to add them using the admin forms.

### Current behaviour

Adding a user that triggers validation errors also triggers outgoing emails. This means that emails to one new user can be sent multiple times. Perhaps other things also happen.

### Expected behaviour

Nothing should change when the form is considered invalid.

### Steps to reproduce

1. Create a new user
2. Mess up one input field (when testing, I forgot to add a number in the first address line)
3. Observe an outgoing email (e.g. when running in development mode, as output of `manage.py`)
