    contact: get info from the tp-contact in constructed (#628315)
    
    Doing it in set_property is racy:
    - The tp-contact property is set. We use the contact to set the capabilities
    of the contact
    - The "capabilities" property has not be defined so GLib sets its default
    value (unknown) and so override the real capabilities of the contact.
