Hi. I'm trying to write a test with ember-network/fetch. The testing section (https://github.com/tomdale/ember-network#testing ) says to ``` npm install fetch-mock ember install ember-browserify ``` Then in a test do ``` import fetchMock from 'npm:fetch-mock'; ``` In a brand new ember-cli project I'm getting -- ``` Could not find module `npm:fetch-mock` imported from `ember-sandbox/tests/acceptance/root-test` ``` repo for reproduction -- https://github.com/stephencattaneo/ember-browserify-issue/ test -- https://github.com/stephencattaneo/ember-browserify-issue/blob/master/tests/acceptance/root-test.js
