[issue5531] unittest: allow failures in tearDown method

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Agreed with Brett and Raymond.
Besides, I'm not sure how getting a failure rather an error changes
anything in the big picture (for my non native English-speaking brain,
it certainly doesn't make a difference :-)).
