Relates to #337
> Was this intended?

Yes for now otherwise it would fail the Travis suite (an additional '_INST' property remained) may come from the base SQLStore or an unclean removal from a previous test.

Would need some effort to filter what is causing it but it is unrelated to this test where I wanted to make it pass +vote (especially for the query engine part from Fuseki) so that in future that can be investigated in isolation knowing that all other tests pass.
