process.stdout.getColorDepth is not a function

Getting a lot of these errors when using power-assert (without babel plugin) in ava tests:

Uncaught exception in test/normalizers/normalizeScraperVenueResults.js

I've found that my local tests fail on the same thing, unless I am running Node version 9.8 or below. After 9.9.0 was introduced, something in the internals seem to no longer support that getColorDepth function.
