[#62] Reverse order of GET/POST in HTTP out test
[#62] Reverse order of GET/POST in HTTP out test

Swap the order of calls to `EmitGET()` and `EmitPOST()` for HTTP output
tests in order to surface the problems:

- GET requests appear to be repeated. For three iterations, 5 GETs and only
  1 POST request can be observed at `StartHTTP()`.
- POST requests are truncated somewhere along the line and cannot be parsed
  by `HTTPOutput.ParseRequest()`. Resulting in:

      Can not parse request POST /pub/WWW/ HTT malformed HTTP version "HTT"

There is an underlying problem with the test that it only checks the request
count, not the type/content of "good" requests.
