We can't rely on lists having the same order in Python3 the same
way we rely on them in Python2. If we sort them first, and then
compare them, this test will be more reliable.
Due to a bug in the equality handler, this test was failing on
CentOS 6 running Python 2.7.13. This PR splits up the test assertions
into several different pieces in order to cover all the possible
use cases, but also pass on CentOS 6.
