Remove tabs with no data

[jungshadow]

Expected behavior

For example, if there's no ballot data, there would be no ballot tab.

Actual behavior

A ballot tab is present with a salty message.

Steps to reproduce the behavior

Search an address in a state without ballot information.

@jared Did we decide to not render tabs that have no data?

@jajohnso I think we mentioned it would be a bit of a nightmare with the routes if we removed them, right? If that's the case, we just need to have a more helpful (salty) message with state/local election official contact info or that the info wasn't in the API. Let me know what would honestly be best (NB: feel free to close if this is a wontfix, but we should probably open up an issue on checking/improving error messages).
