> Jena uses the IRI `<urn:x-arq:DefaultGraph>` internally to represent the default graph within datasets - we need to recognize that on the way out of a `JenaDatasetImpl.stream()` and possibly in the `asQuad(JenaQuad)` converter and replace it with `Optional.empty()` so the default graph appears the same across implementations.
> The `AbstractDatasetTest` should be augmented to do more tests on the default graph, including `.stream()`, `.iterate()`, `.contains()` and `.remove()`1.
