Allow editing of pending users

At the moment if a user is pending we don’t show the ‘change’ link.

This is unhelpful because:
- there’s no way to remove this user
- there’s no way to change their phone number, if the reason that
  they are still pending is because they’ve been unable to receive
  the two factor code at the number they first provided
