MultiHttpBlockConfigTests groovy->java

Note that originally there were five tests in the groovy test, however
the last one, multipleAuthenticationManagersWorks, turned out to be a
duplicate after creating the test
requestWhenUsingMutuallyExclusiveHttpElementsThenIsRoutedAccordingly

As such, the new file contains just four tests.

Issue: gh-4939
