upgrading to ember@2.18 and installing ember-test-helpers leaves module undefined during test hooks

[BryanCrotaz]

This seems like the same symptom as emberjs/ember-qunit#179.

Tests run in PhantomJS and every unit and integration test now fails with undefined is not an object (evaluating 'module.setContext'). A small number fail instead with you must set a resolver with \testResolver.set(resolver)`, but that's probably notember-cli-qunit`.

Can you provide a reproduction?

[BryanCrotaz]

I'm not sure how to - I've upgraded other projects and not seen this. I don't think they're using ember-test-helpers though.

It's a private repo - I could give you temporary access. It's a reasonably small addon - 70 tests,

rebuilt from a new clean addon - installing ember-test-helpers is what breaks it. I'll reopen in there.
