Description of problem:
rhncfg-manager raises an exceptions while handling an exception during a configuration directory deployment.

Version-Release number of selected component:
Spacewalk server 2.4
rhncfg-management-5.10.85-1.el6.noarch

How reproducible:
0) Have an installed Spacewalk 2.4
1) Create a configuration channel
2) In configuration channel chose 'Add Files' -> 'Create File', add a directory, owned by a user that would not be present on the system by default
3) Register a client system in the Spacewalk Server with 'Provisioning' Entitlement
4) On the client system install packages rhncfg*
5) and run:
rhncfg-manager download-channel --topdir=/tmp rmdir_test_channel

Actual results:
[root@test04-64 ~]# rhncfg-manager download-channel --topdir=/tmp rmdir_test_channel

do no try to remove directories which were not created by current transaction

Additional info:

There is another bug 1309003, which is similar to this one, but actually
there is a reason to do it separately.
