RFR: 8306940: test/jdk/java/net/httpclient/XxxxInURI.java should call HttpClient::close

Wed Apr 26 16:16:01 UTC 2023

The tests test/jdk/java/net/httpclient/*InURI.java create a lot of HttpClient instances.
They should call HttpClient::close when the client is no longer needed.

The fix includes some cleanup of the test code, as well as an additional check on the response version.
