Manual email confirm (#2492)

* manual approve email via bw-dev/manage.py

./bw-dev confirm_email USER
(venv) python manage.py confirm_email USER

* add "confirm_email" and "remove_2fa" to autocompletion

* OK, sometimes I feel fooled by this.

The lione was not LONG ENOUGH.

* Change deactivate reason to None

* Whyever this works now

Python in my system is a wondermachine.
