Serve invite pages under virtual host

While ensuring that all hosts are deployed to the chat subdomain, I applied the
same logic to the invite pages too.

However, this broke invites as prosody's HTTP module has a check which ensures
that the page being served is on the same domain as the virtual host, meaning
that invite pages hosted under the chat subdomain would receive a 404.

So, serve invite pages from the domain itself (which is the default config in
prosody). To do this, we must direct such requests from nginx too.
