Fixes a drag-and-drop bug in pluggable lists whose models do not provide a wantsDropSelector.
As you can see in #acceptDrop..., the pluggable list itself depends on the morph to be a TransferMorph. We might want to change #isKindOf: to #isTransferMorph or #respondsTo: in the future. Well, drag-and-drop is kind of important and it may deserve an #isTransferMorph in Morph to be added.
