Issue #28688: Remove warnings.filters check from regrtest 

Reloading the warnings module duplicates filters in warnings.filters. Fixing
the issue is tricky. It was decided to simply remove the check from Python 3.5,
since the bug only impacts Python unit tests, not real applications.

The check is kept in Python 3.6 and newer.
