[JENKINS-9315] Jenkins 1.405 duplicates test results after upgrade from Hudson 1.392

Upgraded Hudson (1.392) to Jenkins 1.405 by dropping in a new WAR file renamed as hudson.war as the upgrade directions at https://wiki.jenkins-ci.org/display/JENKINS/Upgrading+from+Hudson+to+Jenkins specify. Everything looks fine, except we are now seeing Test Results double reporting tests. Each test name within a test class is listed twice. As a consequence total test counts are double what they should be.
