Test the behavior of nginx-proxy when restarted after deleting a certificate file is was using.
1. nginx-proxy is created with a virtual host having a certificate
1. while nginx-proxy is running, the certificate file is deleted
1. nginx-proxy is then restarted (without removing the container)

# nginx-proxy template is not considered when a container is not reachable
Having a container with the `VIRTUAL_HOST` environment variable set but on a network not reachable from the nginx-proxy container will result in nginx-proxy serving the default nginx welcome page for all requests.
Furthermore, if the nginx-proxy in such state is restarted, the nginx process will crash and the container stops.
In the generated nginx config file, we can notice the presence of an empty `upstream {}` block.
This can be fixed by merging [PR-585](https://github.com/jwilder/nginx-proxy/pull/585).
## How to reproduce
1. a first web container is created on network `netA`
1. a second web container is created on network `netB`
1. nginx-proxy is created with access to `netA` only
## Erratic behavior
- nginx serves the default welcome page for all requests to `/` and error 404 for any other path
- nginx-container crash on restart
Log shows:
```

```
## Expected behavior
- no default nginx welcome page should be served
- nginx is able to forward requests to containers of `netA`
- nginx respond with error 503 for unknown virtual hosts
- nginx is not able to forward requests to containers of `netB` and responds with an error
- nginx should survive restarts
