Ember.TEMPLATES is empty (ember-cli-htmlbars)

We're currently using ember-cli 1.10.0, which comes out of the box with ember-cli-htmlbars 0.7.4.

Our app directory is what ember-cli sets up out of the box. There's an application.hbs file in app > templates, and we added a directory app > templates > application where we have all of the partials to be loaded for application.hbs. One of the partials is _google_analytics.hbs.

We keep running into the error Uncaught Error: Assertion Failed: Unable to find partial with name "application/google_analytics", and Ember.TEMPLATES is empty in the console. When we intentionally mess up _google_analytics.hbs, ember server throws an error and fails to compile, so all of the templates are running through the compiler, but Ember isn't able to find them.

Here's our package.json file:

Here's our bower.json file:

    "ember-data": "1.0.0-beta.15",

    "bootstrap-datepicker": "~1.3.1",
    "hopscotch": "~0.2.3",
    "jquery-dateFormat": "~1.0.2"
  }
}

And here's our Brocfile:

/* global require, module */

var EmberApp = require('ember-cli/lib/broccoli/ember-app');

var app = new EmberApp({
  dotEnv: {
    clientAllowedKeys: ['SOME_KEY', 'SOME_OTHER_KEY']
  }
});

module.exports = app.toTree();

We even messed with environments.js and turned on the html-bars feature like so:

EmberENV: {
  FEATURES: {
    'ember-htmlbars': true
    // Here you can enable experimental features on an ember canary build
    // e.g. 'with-controller': true
  }
},

But that didn't work because we aren't using a canary build of Ember. We haven't seen this issue documented anywhere else, so it looks like it's something fairly obvious that we're missing. Any help would be greatly appreciated!
