Origin check for POST requests seems wrong

[benwiley4000]

I noticed when setting up the origin configuration for the fair analytics server that the server side logic doesn't make much sense. It's not possible for the origin configuration to equal both the host and hostname at the same time, and it shouldn't equal either of those since the origin header actually needs to include the network protocol (http:// or https://).

I gave a go at fixing it in my fork and I could make a PR if you'd like: https://github.com/benwiley4000/fair-analytics/commit/15eb9b6d540c9dca9e931e744d4489262b4053ce
