Apply permissions when determining OwnerInfo consumer counts.

NOTE:
A change was made to TestUtil.createEntitlement to add the entitlement
to the specified consumer, instead of just setting the consumer
on the entitlement. As a result, a couple of tests had to be
adjusted as they were expecting the consumer to have no entitlements.
