Describe the bug
The options from 404 host (dead host) from UI (SSL tab, custom tab under cog) are completely ignored and not rendered into the dead_host .conf file

Nginx Proxy Manager Version
npm v2.13.2 has the bug,

but in v2.11.2 it works correctly

To Reproduce
Steps to reproduce the behavior:

1. Create a 404 host, set up correct SSL cert (existing correct cert) and custom options.
2. Check /data/nginx/dead_host/1.conf
3. The file doesn't contain anything from SSL setup or custom options - they are completely ignored
4. So these options don't work

Expected behavior
Options rendered into the .conf file

Operating System
Linux + Docker image jc21/nginx-proxy-manager
