Closes #288.
Previously FURB120 would emit an error for any default arg it found, but in some cases following Refurb's advice would cause an error. The issue is that non-default positional args that follow default positional args cannot be removed, so Refurb should ignore these default values that are "trapped" behind a non-default one.
