Throw exception when json-patch append adds primitive to collection of complex objects

When trying to do an json-patch append to a collection of complex objects, if we provide a primitive such as a string for the value there is no type checking. This causes a type mismatched item to be added to the collection.

Main cause is that org.springframework.data.rest.webmvc.json.patch.JsonPatchPatchConverter#valueFromJsonNode returns JsonLateObjectEvaluator only for complex types. If a primitive value is returned from this method, the value is not checked by the PatchOperation class.
