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.

Reproduce the reported upgrade path from Ember CLI 4.4 through the listed LTS releases, running `ember-cli-update --run-codemods` and then `yarn lint:fix` on the test files. Compare the formatting changes from both commands; done means the codemods and lint fixer agree on formatting rather than undoing or adding changes.
