The storage tab gets it from the cache manager (which gets it via
Dataset.persist()). I think this is what will be displayed when the Dataset is
printed in the repl, I'm not sure if it's also used elsewhere.
Given that there's also a .name method I agree that it would be nice to
keep the schema in here. I'll add it in, but will need to update the tests to
take that into account.
