Follow up of #10732 - Allow string hash values on AR order method

Hello,

This pull request is a follow up of #10732. This is a rebased version with a few improvements:

* Tests are fixed since a `fifth` fixture has been added to the topics collection.
* Remove `assert_nothing_raised` calls since the latter is deprecated.
* Improve a bit the changelog entry.

Let me know if you want me to change anything.

Have a nice day.
