fix(http-server): discard request body if the content-length header i…

[acolombier]

Addresses #2102

Summary

This PR changes the condition of the HTTP server resolving the request body. It assumes that the body is null in case of an explicit Content-Length: 0.

Since in #1990 the decision was made to assume no body in case of no explicit Content-Length other than zero (omitting will assume no body - which seems matching the HTTP/1.1 spec), however I didn't follow the same approach as it could be seen as a minor changes (as apposite to a patch).

Let me know if you would like me to default it to 0 in case if missing as well!

@chohmann This looks to be causing a breakage where requests are accepted when no body is provided, but the body is defined as having one or more required parameters and should thus be rejected.
