[REF] Useradd contact task - Use OO instead of hardcoding "if Wordpress"

[demeritcowboy]

Overview

This should be no change from current - putting it up while it's still in recent memory.

Before

1. Log in as a user who can create users in the CMS.
2. Visit a contact record.
3. From the actions dropdown choose Create User Record.
4. On all CMS's except wordpress there'll be a password field.
5. On wordpress it depends if users can register.

After

Same

Technical Details

Just refactors so that it isn't "if Wordpress" and instead uses the class hierarchy.
