For odd roots of negative values, we need to take the root of the *magnitude* of the number to avoid a NaN from the platform's implementation of `pow`, then restore the sign afterwards. We had the basic logic in place already, but were missing the step of taking the magnitude first. Also modified a test case to find this error.
