Resepect Raw URL setting for query string, too (Grizzly, 1.7.x)

Even with my prior pull request AsyncHttpClient#439 applied, the query string was still escaped twice, when using raw URL. This change fixes it. 

The function addQueryString() - that I commented out - seems to do nothing that has not already be done when building the URI in the Request. Except it does not care for the isUseRawUrl() setting. If there's a subtle difference I did not notice, isUseRawUrl() should be added inside the body of that function.

All of async-http-client tests still pass. com.ning.http.client.async.QueryParametersTest has no tests for raw URLs, though. But our tests now show the same behavior for both Netty and Grizzly.
