Fix unexpected issued_at behavior when date field empty.

Previously before_save and before_create callbacks set the value for issued_at
created_at end of day if no datetime was provided. This prevented records being
saved with no issue date. But it caused unexpected behavior when creating or
updating a donation/purchase/distribution with an empty issued_at field,
silently changing the issued_at date to something potentially incorrect.
