This is a trivial change of removal unused and unnecessary code in the Http2EndExchangeTestCase.java test case.

Apart from that, I slightly changed the way how test fails in case that HTTP2 connection is not correctly established - I unified this failure with other failures in the test.

There is no other problem in the test as it is passing just fine. I just got around this when I was investigating something else.

In case of curiosity, you can check it is still okay e.g. by:

mvn test --show-version -Dmaven.javadoc.skip=true -DskipUnitTests -Pproxy -Denforcer.skip -Dtest=Http2EndExchangeTestCase.java -DfailIfNoTests=false
