Summary0006444: merchant backend returns 100 continue before 404 on POST /private/orders
DescriptionInstead of failing immediately, the backend first 404s and then fails shortly thereafter with a 404.
Somehow we don't do the right thing (TM) and check early on for the 404 failure case.

Also odd: we still seem to fail before the actual upload succeeds, at least with my current WooCommerce test.

Steps To ReproducePost to backend where no instance is configured. Transcript from wireshark:

POST //private/orders HTTP/1.1
Host: backend.test.taler.net
Accept: */*
Authorization: ApiKey sandbox
Content-Type: application/json
Expect: 100-continue

HTTP/1.1 100 Continue

HTTP/1.1 404 Not Found
Server: nginx
Date: Sat, 25 Jul 2020 10:46:15 GMT
Content-Type: application/json
Content-Length: 57
Connection: keep-alive

Turns out this is the nginx reverse proxy's 100 continue. It just doesn't wait for the backend to react :-(.
