bpo-37223, test_io: silence last 'Exception ignored in:' (GH-14029)

Browse source 
Use catch_unraisable_exception() to ignore 'Exception ignored in:'
error when the internal BufferedWriter of the BufferedRWPair is
destroyed. The C implementation doesn't give access to the
internal BufferedWriter, so just ignore the warning instead.
