adding/editing contacts to the google addressbook fails

Issue generated from Tuleap's migration script. Originally submitted by: Stepan Salenikovich (ssalenik)

The e_book_client_add_contact_sync method returns as 'true', but the contact is never added.

The e_book_client_modify_contact_sync fails with an error ('no such contact exists').

Either there is an error in the use of the api or there is something missing in the account setup itself... or it is simply not supported by EDS...
