Pascal Hartig 719dd65340 Warn when console.error is used in tests
Summary:
It's a bit hacky but apparently the recommended solution:
https://stackoverflow.com/questions/28615293/is-there-a-jest-config-that-will-fail-tests-on-console-warn

This will bail when a call to `console.error` is used in a test.
If you *need to* use console.error in a test, then mock it.

This will likely not pass yet, but let's fix all failures and then land it.
