Fixed an issue where saving Config Overrides without all 3 environments set would crash the extension.

Description

The <Overrides/> React component was looking for the datastreamId for every config overrides environment, even if that environment had no settings. If an environment had no settings, then it would be looking for a datastreamId on undefined, which crashes the extension.

Nice. Is this unit testable?

Not really, since we haven't don't do unit tests on React components right now. We could probably write a functional test around it though.

I'd like to see a functional test that reproduces this bug.
