rename test/entities to test/00entities

I suspect that the reason my tests aren't triggering the
entity code is because it is loading the tests into
the same process in alphabetical order, which means
the elasticsearch module is being loaded before
the entity store.
entity commands are working?

but i needed to call this.prior after indexing,
otherwise index creation logic was non-determinative

it's also impossible to test whether search is
working without that.
