__trunk_address__ in WSS url is not getting replaced

[lpotthast]

I'm now seeing these browser-console-errors using the latest released trunk-ng build.

WebSocket connection to 'wss://{{__trunk_address__}}/_trunk/ws' failed:

Seems that the html_address_middleware is not working as it should..

That's interesting because (aside from "works for me") the replacement string is lowercase, while it actually is uppercase.

So, the only case where this would seem to fail is when the Host header is not sent in the request from the browser (or something intercepts this in the middle).
