For a request body with a single GraphQL request, the HTTP POST middleware checks for the batchOperations query parameter, which creates the query feature and parses the query collection on every POST request, even when the request has no query string.

This PR checks QueryString.HasValue first and reads the query collection only when the request has a query string.
