Description

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1372917

Description of problem:
When trying to view or edit a host group the following error is seen in the webui:
undefined method `name' for nil:NilClass
The entire traceback can be found here: http://pastebin.test.redhat.com/40871

How reproducible:
So far, unable to reproduce.

Steps to Reproduce:
1. Attach properties to host group (puppet modules, kickstarts, etc)
2. Remove property being used in host group
3. Attempt to view/edit group

Actual results:
Removing a property being used by a host group renders the group inaccessible

Expected results:
Removing a property in use by the group should simply remove the property from the group and still be able to be edited.

Actual reproducer:
1. Create HG with os, arch and content view and save.
2. Edit same HG and remove the arch and os, save.
3. Reopen the HG - it crashes.
