Fix issue #13017: opEquals for null std.typecons.Nullable

I was getting sick of this not working, and there have been multiple bug
reports on this, so I'm just fixing it. With these changes, using == and
!= on null Nullables will not result in an AssertError but instead will
consider them equal if they're both null, equal if they're both non-null
and have the same value, and not equal otherwise.
