Introduced in #1037.

Fix - Allowed nil observations to be updated by form element status rules as this is the common use case of using these rules.

This has the side effect that any editable form elements which have form element statuses cannot be edited to completely remove the value. Fixing this side effect might require significant refactoring of the original story.
