Change nonsense non-const Date* GetNullDate() to const Date&

* first, a non-const Date* may leave the impression that one could change the
NullDate through the pointer, which is only partly successful; luckily no one
did that
* second, there is always a NullDate so checking for nullptr is superfluous
* third, the pointer was dereferenced (maybe after a check) everywhere to
obtain the NullDate, luckily..
