[423052] Do not leverage PackageNotFoundException after demandPackage

demandPackage should not return null when a namespace is declared: it
prevent migration of known (deleted) EClasses

PackageNotFoundException was thrown but we explicitly use XMLResource.OPTION_RECORD_UNKNOWN_FEATURE to record unknown features and any type. It is still possible to detect the unkown feture using XMLResource.getEObjectToExtensionMap().
