Use case for the steps to reproduce

When extrenal changes are done on Session, the session is reloaded. If a diagram editor is opened during the reloading, its listeners (GMFDiagramUpdater) use the old Diagram (proxy) instead of the new one.

Steps to reproduce:
* Imports the project "SampleProject" of the sample.zip file
* Open diagram "root package entities"
* Modify the files "representations.aird" and "My.ecore" outside of eclipse (just add a blank line in the file)
* In Eclipse, launch a refresh on the prject
* Add a new package in "newPackage1" --> There is error in errorLog

Impossible to find an interpreter - Could not find a session for model element : org.eclipse.emf.ecore.impl.EReferenceImpl@3a6cc951 (eProxyURI: platform:/resource/SampleProject/My.ecore#//newPackage1/NewEClass1/newEReference1):
