CSS preprocessor is not active if the app is named differently from the package.json#name field

[NullVoxPopuli]

I ran in to this as a laziness when copying the classic-app in #174
and without changing code, you can set name in ember-cli-build.js:

module.exports = function (defaults) {
  const app = new EmberApp(defaults, {
    name: 'classic-app',

and the modulePrefix in config/environment.js:

module.exports = function (environment) {
  const ENV = {
    modulePrefix: 'classic-app',

this works with all features of ember-cli, but the css preprocessor is expecting the name to match the package.json#name field (and likely other file filtering as well).

I'd consider this a bug -- but the work-around is easy enough for now (rename all your imports of the custom name to match the package.json#name)
