According to the spec[1], when creating a `DurationFormat` instance with `new Intl.DurationFormat(locales, { fractionalDigits: undefined });`, `Intl.DurationFormat#resolvedOptions().fractionalDigits` should be `undefined`. However, in the current JSC, it is `0`. This was occurring because, according to the spec[2], the `fallback` argument of the `GetNumberOption` abstract operation should be `undefined`, but we were passing `0`.
