Not working with Embroider

[danwenzel]

Reproduction here: https://github.com/danwenzel/embroider-issues/tree/css-modules-sass

I've got the beta embroider version of ember-css-modules installed (1.3.0-beta.1). After adding ember-cli-sass and ember-css-modules-sass, scss styles are not working.

• For pods components, getting

Uncaught (in promise) Error: Unable to resolve local class names from embroider-test/components/pods-component/styles; does the styles file exist?

• For classic components, I'm not seeing an error, but there are no styles applied
