Rolling forward the change to open source JUnit integration tests.

Fixed failures by removing the (expected) failing XML reports from the path, to stop Jenkins from reporting a failure despite passing tests.

After removing the XMLs I see jenkins passing where it was previously failing: http://ci.bazel.io/job/Gerrit-bazel-tests/419/ (caused by an un-clean version of this change https://bazel-review.googlesource.com/c/9039/)

<Rollback history below>

*** Original change description ***

Automated [] rollback of commit 9822151.

*** Reason for rollback ***

Jenkins reports the tests as failing. See bazelbuild#2554 for more details.
