Hidden fields still in the tab index on the add panel

Description

If you create a user and the email server is set up so the default value for Send email to setup password is true, if you tab through the fields you'll notice you are tabbing across hidden fields.

This is sometimes visible if you have auto-complete opening the password fields. This will be visible even though the field is not.

Steps to reproduce

Steps to reproduce the behavior:

1. Enable email configuration
2. Create a new user
3. Leave the default config for Send email to setup password
4. Tab through the fields

Expected behavior

The password fields that are hidden when the boolean Send email to setup password is true - should be disabled so they are not included in the tab index.
