title: User cash on delivery in django-oscar
body: <p>I'm working in e-shop project using <code>django-oscar</code> and i trying to add COD support. I'm using <a href="https://github.com/michaelkuty/django-oscar-cash-on-delivery" rel="nofollow noreferrer"><code>django-oscar-cash-on-delivery</code></a>.</p>
  
  <p>I did the <a href="https://github.com/michaelkuty/django-oscar-cash-on-delivery/blob/master/README.rst" rel="nofollow noreferrer">steps</a>, you can see my configuration:</p>
  
  <pre><code>THIRD_PARTY_APPS = [
      'jet.dashboard',
      'jet',
  
      'axes',
      'cashondelivery',
      'django_extensions',
      'oscarapi',
      'paypal',
      'payu',
      'rest_framework',
      'robots',
      'widget_tweaks',
      'webpack_loader',
  ]
  </code></pre>
  
  <p>And created an app called <code>apps</code> and loaded properly:</p>
  
  <pre><code>INSTALLED_APPS = THIRD_PARTY_APPS + PROJECT_APPS + [
      'django.contrib.admin',
      'django.contrib.auth',
      'django.contrib.contenttypes',
      'django.contrib.sessions',
      'django.contrib.sites',
      'django.contrib.messages',
      'django.contrib.staticfiles',
      'django.contrib.flatpages',
  ] + get_core_apps(
      [
          'apps.shipping'
      ]
  )
  </code></pre>
  
  <p>In <code>apps</code>folder i created an <code>apps.py</code> file with this code inside:</p>
  
  <pre><code>from oscar.app import Shop
  
  # from apps.checkout.app import application as checkout_app
  from cashondelivery.app import application as checkout_app
  
  
  class ApplicationShop(Shop):
      checkout_app = checkout_app
  
  
  application = ApplicationShop()
  </code></pre>
  
  <p>But i can't understand why Oscar doesn't show me the checkout template with cash on delivery method.</p>
  
  <p>This is my structure folder:
