Screen log

Description of problem:
Syncing a CDS with un-associated repositories doesn't seem to remove the contents from it---the rpms are still present. Details in screen log.

Version-Release number of selected component (if applicable):
RHEL-6.3-RHUI-2.1-20120705.0-Server-x86_64-DVD1.iso

How reproducible:
Always

Steps to Reproduce:
1. Associate Red Hat (and a custom) repository with a CDS
2. Synchronize CDS cluster nodes
3. Un-associate the repository from the CDS cluster
4. Synchronize CDS cluster nodes
5. on cds nodes /var/lib/pulp-cds/packages/ does still contain "unassociated" rpms
  
Actual results:
Contents isn't removed with un-associated repository CDS synchronisation

Expected results:
Contents is removed when syncing CDSes with some repositories un-associated
