Along some minor changes, TF frontend requests now directly
submit the InternalRequest to the core's application chain
without explicitly transitioning them to a ServerRequestInterface
since TF InternalRequest now directly extends core's ServerRequest.

This simplifies the class chain and is the general way to go.

* tests are adjusted to test against adjusted sync between
  'body' and 'parsedBody'
* tests added for request uri query arguments and request
  queryParams syncronization in different constellations
