CloudBees Replication Parent 2137

Previously on the $JENKINS_URL/computer and $JENKINS_URL/manage/computer pages, the High Availability (HA) build queue widget incorrectly showed an empty queue even if items were actually enqueued, while on the $JENKINS_URL and $JENKINS_URL/manage pages, the queue was correctly displaying them. All four pages now display the High Availability (HA) build queue widget and list items that have been enqueued.
