    Workaround lack of way to save contacts via Contacts right now
    
    We want to propmt people to save contacts in the Contacts app by opening
    the contact in the app and prompting them to save it there, but
    functionality for this hasn't landed in Contacts yet. So for the moment,
    just save directly via Folks, then open in Contacts.
    
    See #133, GNOME/gnome-contacts!66
