routes/index.ts: register proxy routes before body-parser

Any json or urlencoded request bodies were being consumed by body-parser
before they could be proxied. That's why requests without Content-Type
were proxied correctly as body-parser would not consume their body.

This allows the http-proxy package to passthrough the request body correctly
in all instances.

Closes #2377
