[issue41197] Async magic methods in contextlib.closing

[Serhiy Storchaka]

Warning is not error. It may left unnoticed, especially if the code is executed on server. And in this particular case turning the warning into exception by setting warning filters does not help, because it would be raised in the context where exceptions are swallowed.
