`Sort.descending` and `Sort.ascending` lose null handling and case-sensitivity flags

[jansu76]

I was puzzled for a while when I used Sort.descending(). Javadoc says

Returns a new {@link Sort} with the current setup but descending order direction.

I had set ignoreCase to true on Order but switching to descending sorting negated that change. I understood "with the current setup" to keep ignoreCase setting as is.
