7155	dates() querysets don't work after qsrf	fcaprioli@…	nobody	"After queryset refactor merge, a .dates() DateQueryset won't work on a null=True DateField. 

During query setup, the queryset adds a .filter(fieldname__isnull=True) instead of .filter(fieldname__isnull=False) to avoid parsing null dates, so the resulting sql returns an empty list (or raise errors if there actually are null fields in the db).

I've attached a patch that fixes the problem"		new	Database layer (models, ORM)	dev			post-qsrf		Unreviewed	1	0	0	0	0	0
