User registration on Cuddlers CMS

User registration on the Cuddlers CMS after user has followed the states:registration:* leg of the customer journey.
So something like:

```
return tester
  .setup.user.state("states:registration:confirmTermsAndConditions")
  .setup.user.addr('+27799938631')
  .input("1")
  .check.interaction({
    state: "states:registration:registrationFailed",
  })
  .run();
```
Could that work?
