Comment (by joehoyle):

 Added a patch to pass the 3rd arg to the filter. This arg is "Was the
 default value passed by the caller" which is used to choose if the
 `register_setting` default should override the the `false` default. In
 this case, like `update_option`, it should.

 I added a unit test for this rather specific case where `alloptions` is
 not loaded, which before the patch will fail from a notice.
