Remove communication settings for non-active users [MJ-698]

The list of emails that the user can choose from was being created with no contents. That list is populated with all of a user's active email addresses. As the user has not activated that account yet, the account's primary email has not been validated.

As there is nothing relevant to a non-activated user in the communication settings, I just disallowed it from displaying. If that is inappropriate, I can do something else.

All tests pass.
