Summary0003817: Loading a scene without camera produces inconsistent state

Sometimes MRML scene files don't contain camera nodes (to keep those scenes short and concise).
Loading such scenes may lead to view nodes without any camera node.
That can potentially generate crashes because code always expects a camera node for any given 3D view.

Steps To Reproduce

Start Slicer
Load scene file with no Camera XML element
Close scene
Load same scene file again
-> open python console and

c = slicer.mrmlScene.GetNodeByID('vtkMRMLCameraNode1')

Additional Information

Regression from 0002758

It is likely due to the commented lines in vtkMRMLCameraDisplayableManager::UpdateCameraNode():
vtkDebugMacro("why am I here? I have a camera node already!" << unassignedCamera->GetID() << " for view node " << viewNode->GetID());
