Creating a User in the admin interface causes the password to not be hashed

[nfoert]

Describe the bug Creating a User in the admin interface will create the password in plain text. You'll not be able to sign in since the server is expecting a hashed password.

To Reproduce Create an account in the admin interface. The password is stored as plain text.

Expected behavior The password should be hashed on save and stored correctly.

Thanks @sree-hari-s for reminding me of this in #24.
