JSON-LD resources endpoint should return consistent ordering of data in arrays

[jacobtylerwalls]

@aarongundel and I noticed that the the JSON-LD endpoint returns arrays of data that aren't deterministically ordered.

Adjusting this test to repeat the GET and assert equal results gives occasional failures (to be clear, not suggesting we add this as a potentially flaky test, just demoing the issue):
