Django test suite still has an occurence of assertEquals, removed in Python 3.12

[Michel Alexandre Salim]

Python 3.12, shipping in the upcoming Fedora 39, finally removed the deprecated assertEquals in favor of assertEqual. The Django test suite mostly use the latter already, but there is one occurence of the former left. It should be converted.

Test failure on Python 3.12:

AttributeError: 'FilteredRelationTests' object has no attribute 'assertEquals'. Did you mean: 'assertEqual'?
