[#587] unique_name now hashes the call tuple for a random seed.

This will allow tests that depend on irods.test.helpers.unique_name
to run in Python3.11+.

The aforementioned hashing was internally and noiselessly performed
in Python 3.8 and before, but was deprecated in 3.9 and then
discontinued in 3.11.

As a result, we'll now perform it ourselves.
