["Matthew D. Wood" <woodm1979@xxxxxxxxx>]

Public bug reported:

On the  project/access_and_security/security_groups/<detail> page, some
errors inside the
openstack_dashboard/dashboards/project/access_and_security/security_groups/views
DetailView._get_data method are still resulting in a None being
returned.  This causes an error in the DetailView.get_data method as
NoneTypes clearly don't have a .rules attribute.

I'm not sure why the error is sneaking through the exceptions.handle
above, but they most definitely are.  Perhaps Ana Krivokapic's changes
here: https://review.openstack.org/#/c/84109/ may eventually solve this,
but it's unclear.

In the mean time, and potentially correct overall, if a None is
returned, the get_data method should return an empty list instead of
throwing an exception.
