This patch fixes the test suite to allow any order when listing the
members of a JSON object.  Aeson (being true to the JSON specification)
does not specify an order for objects.  In practice, the order depends
on your processor architecture.

See <https://github.com/bos/aeson/issues/568> for a discussion resulting
in a similar patch fixing the Aeson tests.

See <https://github.com/fosskers/microlens-aeson/issues/1> for the
upstream bug report.
