Formatting applied by `ember-cli-update --run-codemods` disagrees with `yarn lint:fix`

I'm working on updating an app from `4.4` up to `6.4` by jumping from LTS release to LTS release (4.4, 4.4, 4.12, 5.4, etc...).

For each new LTS release when I run `ember-cli-update --run-codemods` it makes purely formatting changes to nearly every test file in the project. And then if I run `yarn lint:fix` it undoes some of those changes and/or makes a different set of changes.

It would be nice if those two things agreed about the proper way to format stuff.

Apologies if this isn't the right place to raise this issue. If that's the case please point me to the proper place.
