Config schema errors

Is this the same as 🐛 [regression] Schema changed incorrectly. Active ? I believe this only affected the draggableviews demo; I didn't think it affected anything else.

The linked issue is just part of the problem. There are other problems with the config schema as I listed in the description. It affects any view which uses the DraggableViews field and/or the DraggableViews Weight sort. If the config schema checker is enabled, it will fail while saving the View and results in a WSOD.
