16917	Listing leftover content types for missing models breaks admin	Ivan Sagalaev	Ivan Sagalaev	If during the lifecycle of the project some models got removed and their registered content types still remain in the DB the admin (or any such code for that matter) crashes trying to display content types. This happens due to {{{ContenType.__unicode__}}} relying on {{{self.model_class()}}} to be always available. This is a recent regression from [16839].
