Eliminate spurious notifications from PAP

Tracked it down to the following sequence:
- policies were deployed to the pdp
- received a request to undeploy a policy
- generated a notification for the formerly deployed policy
  - this should not have been generated
- undeployed the policy
- received a response from the pdp indicating the policy had
  been undeployed
- generated a notification indicating the policy was undeployed

Removed the code that generated a notification when a policy is
initially moved from deployed to undeployed (or vice versa).
