TT#139455 instances-info: Make output reproducible

We need to specify what to sort on, otherwise we are sorting based on
the references and not the actual keys. Add specific code blocks to sort
on the hash keys we are interested in. This makes the output
reproducible which makes the tests always pass, instead of randomly
failing depending on the ordering used randomly by perl.

Fixes: commit 83003649e3
