Inheritance info must be stored inside scope on test_v3_assignment

[Samuel de Medeiros Queiroz]

The method _build_role_assignment_url_and_entity(..) creates expected role assignments depending on provided parameters.
When an inherited role assignment is requested, it is putting 'OS-INHERIT:inherited_to' info inside the main body of the entity, instead of inside the 'scope' key.

This reflects on tests, making an assert to never occur [1].
