    e-d-s: update the Avatar Details test
    
    Now that we've reworked avatar handling and we've
    introduced an Avatar cache, the avatars associated
    to a newly created e-d-s contact might not be immediately
    available after the corresponding Edsf.Persona is created.
    Hence we need to listen to notifications for the avatar
    property.
