description:
Update the test a little so that is possible to pass
(if date fails, because of bad or out of range input
to parsedate, it cannot be expected to output the
expected result).

Remove the atf-expect-fail now that parsedate() should
detect overflows, and fail, causing date to fail, rather
than simply producing bogus results.
