      TestJobTrackerRestart failed because of stale filemanager cache (which was created once per jvm). This patch makes sure that the filemanager is inited upon every JobHistory.init() and hence upon every restart. Note that this wont happen in production as upon a restart the new jobtracker will start in a new jvm and hence a new cache will be created.
