expectWarning() and friends have been deprecated in PHPUnit 9.6, and
removed in PHPUnit 10. Unfortunately, there is no simple replacement
because PHPUnit no longer converts them to exceptions in the first
place. In fact, Sebastian Bergmann explicitly stated that he does not
consider the use case of
> a library developer to verify a code block warns its consumer when
> certain action is performed
worth supporting.
So, add an ad-hoc replacement for all the deprecated methods. This is
quite ugly, but it's simple enough given the low number of usages.
On the bright side, this new method does not halt the test when the
warning is triggered. This seems to align with the developers'
expectation, seen in a few existing tests, that any code following the
notice will be executed.
