Eliminate extra status code

[benjamingeer]

When Sipi returns JSON in response to an HTTP request, it returns two status codes:

1. The standard HTTP status code.
2. Another status code inside the JSON.

This is confusing and error-prone, and seems redundant. There are cases where Sipi returns HTTP status 200 (OK), but the JSON contains a status code indicating an error: see dasch-swiss/dsp-api#266 .

Can we get rid of the error code inside the JSON, and just use HTTP status codes?

I need some more information to locate the problem: Under what circumstances results this problem. Is it from a Lua script or SIPI intrinsics? Please indicate the URL that produces the problem!
