A couple of things, get_contacts_sync is an instance method so should
just do:

client.get_contacts_sync(...)

Also, the e_book_client_get_contacts_sync() is badly annotated so the 
Contacts out param is not being picked up by gobject-introspection. I am
pushing a fix for that now. 

Finally, asking around in #gobject-introspection, out params aren't used
as such by pygobject but they are returned to yoy. So in this case
you'll end up having to call (once you get a corrected GIR file for
e-d-s):

ret, contacts = client.get_contacts_sync(query_string, None)

Cheers,
