Issues with Embroider staticHelpers: true

[danwenzel]

Similar to #160

Reproduction here: https://github.com/danwenzel/embroider-issues/tree/css-modules, but change staticComponents: true to staticHelpers: true in ember-cli-build.js

I've got the beta embroider version of ember-css-modules installed (1.3.0-beta.1). When turning on the staticHelpers: true embroider option, ember-css-modules cannot seem to find the local-class helper:

Error: Compile Error: local-class is not a helper

Also, I tried to debug by doing a stage-1-only build, but that threw a build error:

> STAGE1_ONLY=true ember b

Build Error (BroccoliBridgePlaceholder)

BroccoliBridge placeholder 'modules' was never fulfilled.

staticHelpers should now be supported in the 1.3.0-beta.2 release. Please give it a try and let me know if you run into any issues!
