`listify()` now supports empty weak references #531

Closed thedrow closed 3 years ago

thedrow commented 3 years ago

If you attempt to listify an empty weak reference you get a ReferenceError since comparing their type to something is no longer possible. Instead, just return a list containing the object.

thedrow commented 3 years ago

If you're wondering why this is important, this happens when you try to remove a model which is a weakref to an actual object. There are more problems but this solves the most basic one.
