On Rails 4.2, the hostgroups_count cached counter on Puppetclass is now getting updated when a HostgroupClass record is created. This causes the following test to fail, as an audit entry is created for the HostgroupClass and a second for the new hostgroups_count attribute update:

  1) Failure:
HostgroupClassTest#test_0001_when creating a new hostgroup class object, an audit entry needs to be added [test/unit/hostgroup_class_test.rb:13]:
"Audit.count" didn't change by 1.
Expected: 2
  Actual: 3

The second audit entry looks like:
