There are no tests for a full build

We don't currently execute any kind of test to ensure a full build actually works. Such tests would've caught the root cause of today's outage.

I'll work on implementing those tests next week.

As a short-term thing, I think it would be fairly easy to add unit tests that we're using the crates.io API properly.
