admin page template error when django-rq installed but webhooks disabled

[candlerb]

Note: this has been reported several times before (e.g. #2395, #2509, here, here, here, here). Here is how to reproduce it.

Environment

• Python version: 3.5.2 (Ubuntu 16.04)
• NetBox version: 2.4.6

Steps to Reproduce

• Install django-rq package: pip3 install django-rq (which is a documented optional step)
• However, leave WEBHOOKS = False in configuration.py
• Start netbox
• Navigate to /admin/

Expected Behavior

Netbox would show admin page as normal

Observed Behavior

With DEBUG = True:

Internal Server Error: /admin/
Traceback (most recent call last):
  File "/usr/local/lib/python3.5/dist-packages/django/core/handlers/exception.py", line 35, in inner

  File "/usr/local/lib/python3.5/dist-packages/django/template/response.py", line 81, in rendered_content
    template = self.resolve_template(self.template_name)
  File "/usr/local/lib/python3.5/dist-packages/django/template/response.py", line 65, in resolve_template
    return get_template(template, using=self.using)
  File "/usr/local/lib/python3.5/dist-packages/django/template/loader.py", line 19, in get_template
    raise TemplateDoesNotExist(template_name, chain=chain)
django.template.exceptions.TemplateDoesNotExist: django_rq/index.html

Workaround

pip3 uninstall django-rq if you are not using webhooks

I found that someone already submitted a fix in PR #2408.

I can confirm that the problem goes away when I apply this.
