Fix tests that depend on CVE 2016-7078
Following #16982 - there were some tests in Katello (much less than in Foreman due to the requirement for Orgs) that relied upon this vulnerability to work.
Fixes #17266 - Fix tests that depend on CVE 2016-7078
A small number of tests in the Katello codebase depended on regular
users being able to see objects without organization/location. This is
now fixed in core through a CVE (users shouldn't view stuff they're not
scoped to see), so in order for Jenkins to pass, we need to make Katello
tests pass with it too.
