If the model file source of a diagram is deleted, the exception below is logged. What's the point? Perhaps you could provide a do you want to restore wizard, but in the log. Just clean up. Much better if there wasn't a bloated *.aird file. One diagram file per model file would enable the user to retain control just like earlier tooling did.

The problem persists after a repair, whioh removes the dead diagram elements, but not the semantic reference to the deleted file in <semanticResources> and <ownedRepresentationDescriptors
The resource removing is handled if the Sirius Session is opened. We should also handle the case where the resource has been removed with closed session.
