AbstractCreationAndUpdateRdfTests requires at least one instanceShape property value to update a resource

See https://github.com/eclipse/lyo.testsuite/blob/1f331b3c4ddbbb09c0ced18e121afcfd379ea458/org.eclipse.lyo.testsuite.server/src/main/java/org/eclipse/lyo/testsuite/oslcv2/core/AbstractCreationAndUpdateRdfTests.java#L353

https://docs.oasis-open-projects.org/oslc-op/core/v3.0/ps02/core-shapes.html#CommonPropertiesShape does not require this property and does not even include a SHOULD CC to encourage it.

@jamsden could you please check your notes? I recall we had long OP conversations on shapes, esp. if there are multiple shapes on a CF endpoint. But I don't recall if we discussed having shapes on created resources for their subsequent updates.

CreationFactory oslc:resourceShape is Zero-or-Many as the constraint is optional. However if a specific application needs the constraint, it could add the assertNotNull above.
