bug(promisify): audit usage of promisify #304
Description
We were able to duplicate a cb() not called error by calling into an erroneously promisified method. Let's audit out use of promisify, at least in the cli itself if not the other dependencies, to see if we can make them less likely to happen.
WHY they happen is something a little harder to track down and will take a few more iterations of cleanup on the cli to get to a better place for debugging.
