isLeapMonth is a component in Date. Add one more XCTAssert for isLeapMonth in test_recreateDateComponentsFromDate.

We haven't traditionally always set this value (sometimes it is nil, depending on calendar). Is there something in particular we are trying to validate here?

Thank you for your review, @parkera . No particular, just see the test case that cover almost paramaters without it, and I would like to add it into test case.

Dear @parkera ,

It seems Swift Test macOS Platform has the problem. I have observed some previous merged PRs that have also failed with the Swift Test macOS Platform.

Thanks,
Lam
