This regression bug was caused by the error page using the `codimd/head`
template. This resulted in error messages like this:
```
ReferenceError: /codimd/public/views/error.ejs:5

4| <head>
>> 5| <%- include codimd/head %>
6| <link rel="stylesheet" href="<%- serverURL %>/css/center.css">

The fix for that is rather trivial. We simply provide an empty array of
metadata when generating the error template.

- image and URL properties are only included if
the server url is set, because opengraph
protocol does not support relative links

In order to simplify the communication with security researcher and
allow reporting of issues, this document should provide a rough idea
about:
1. What versions are supported
2. Who to contact
3. How to send findings properly secured
4. What to expect from an approved security issue
5. What if it's not considered a security issue
