        Tries to locate the syntax for the type reference that the user used in the original code. Especially interesting for nested types, where one could prefer the (arguably) more explicit (or verbose) Resource$Factory with an import of org.eclipse.emf.core.Resource over the probably shorter Factory with an import of org.eclipse.emf.core.Resource$Factory. The function relies on a node model to be available. Otherwise the actually referenced type is used as the preferred type.
        Parameters:
        owner - the referrer to the JVM concept.
        reference - a reference to a JvmType or JvmMember that is declared in a type.
        Returns:
        the referenced type or one of its containers.
