[issue24694] callables registered in TestCase.addCleanup should be run before tearDown

[Charles-François Natali]

Charles-François Natali added the comment:

I understand the risk of breakeage, but that's still broken, because
we break LIFO ordering.

I'd been using addCleanup() for years and never bothered looking at
the documentation - which is admitedly a mistake - because LIFO
ordering is the natural behavior: since addCleanup() is called once
the test has been entered - so after setUp, logic would expect it to
be undone before tearDown.

But I guess that ship has sailed...
