Description

When you use the Workflow or Coordinator Notification features, Oozie can end up queuing up a lot of WorkflowNotificationXCommand and CoordActionNotificationXCommand. This happens even if there's no notification configured on the job (which I imagine is most of the time); in this case, the execute method simply does nothing. This is wasteful and clogs the queue up.

We should change the code so that it doesn't queue up one of these Commands unless there's actually a URL to notify.
