RFR: 8254802: ThrowingPushPromisesAsStringCustom.java fails in "try throwing in GET_BODY" [v2]

[Daniel Fuchs]

> Hi,
> 
> Please find below a fix that fixes an issue in Http2TestServerConnection - where the 
> connection will be closed by the test server if the test server receives a RESET from the client
> after the stream has been closed.
> 
> This issue has made the ThrowingPushPromisesAsStringCustom test fail from time to time, but
> the debug traces have eventually revealed what was the issue:
> 
> DEBUG: [readLoop] [818ms] FramesDecoder Got frame: RESET: length=4, streamid=24, flags=0 Error: Stream cancelled
> TestServer: Unexpected frame on: 24
> RESET: length=4, streamid=24, flags=0 Error: Stream cancelled
> Http server reader thread shutdown
> java.io.IOException: Unexpected frame
> at Http2TestServerConnection.readLoop(Http2TestServerConnection.java:776)
> at Http2TestServerConnection$ConnectionThread.run(Http2TestServerConnection.java:438)
> Server connection to /127.0.0.1:39830 stopping. 5 streams
