    Set ESource's connection-status to disconnected on EBackend's dispose
    
    As long as the ESource is associated with only one EBackend instance,
    which it is, then the backend dispose means that the source is not
    connected anymore, thus mark it as such. This may allow to not show
    credential prompts for sources which are not interested in them anymore.
