Fix ManagedProfileTest failures

ag/9809613 updated the user restriction APIs to now be callable on the parent
instance, however, the tests in ParentProfileTest have not been updated.
This was solved by adding the user restriction APIs to the whitelist of public
API methods that are supported on a parent profile.
