Title: Do not modify example ancestry when dumping errors

This causes bugs (Notably that after blocks / transaction rollback is not executed properly)
when errors are dumped while examples are still running
as is done by [rspec-instafail](https://github.com/grosser/rspec-instafail) and therefore fuubar formatter.
