Fix broken error template due to missing opengraph

Browse source 
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
    3|
    4| <head>
 >> 5|     <%- include codimd/head %>
    6|     <link rel="stylesheet" href="<%- serverURL %>/css/center.css">
    7| </head>
    8|
/codimd/public/views/codimd/head.ejs:7
    5| <meta name="apple-mobile-web-app-status-bar-style" content="black">
    6| <meta name="mobile-web-app-capable" content="yes">
 >> 7| <% for (var og in opengraph) { %>
    8| <% if (opengraph.hasOwnProperty(og) && opengraph[og].trim() !== '') { %>
    9| <meta property="og:<%- og %>" content="<%- opengraph[og] %>">
    10| <% }} if (!opengraph.hasOwnProperty('image')) { %>

```

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