Describe the bug:

In cases where there's no response code for a down check in the Heartbeat detail page, we display a badge with no text. In this case the badge should be omitted.

Steps to reproduce:

1. Create an instance where there's no response code. In my case, my system doesn't have IPv6 enabled, and I ran a monitor like:

- type: http
  id: httpcheck
  name: HTTP_CHECK
  urls: 'https://news.google.com'
  schedule: '@every 45s'
  mode: all

2. Load up the detail page
3. See screenshot

Expected behavior:

We should show no badge.
