This is a followup to PR #1211 to use promises everywhere and migrate away from `test.cb()`. The `test.cb()` function is removed in a future version of ava. I made an attempt to convert the skipped shell.cmd() async test cases, but async functionality isn't implemented so it's possible the test conversion is not totally correct.
