Figure out why deployed site with Smarty Streets disabled is not actually disabled

[hartsick]

See #67

porta just ran a quick validation on the app that has smartystreets disabled:

email address presents as optional (no *)
email address is optional (was able to submit the request and got to confirmation page)
was unable to check to see if on the persisted info, there's a way to discern whether an entry was one run with smarty sheets disabled or enabled. (presume we could detect that via absence of the JSON response).

working hypothesis:

I'm looking at that server and it's not what I expect it to look like if smarty was actually disabled—I suspect the env var isn't set correctly in the environment? will look into in the morning

Closing, as I think this was resolved by #166
