Description of problem:
With the latest continuous integration build of RHSM, a call to the refresh module is throwing a Traceback "AttributeError: 'module' object has no attribute 'BadStatusLine'" when trying to call refresh after the registered consumer has been deleted server-side.  Rather than a hitting a traceback, we should be told that "Unit {UUID} has been deleted".


Version-Release number of selected component (if applicable):
[root@jsefler-rhel6 ~]# subscription-manager version 
server type: Red Hat Subscription Management
