A new name of an address book won't get synced

[ally9335]

Baikal version: 0.10x

Expected behaviour:
When an address book is renamed, a new name should be syncronized with all the clients.

Current behaviour:
For the clients, the name of an address remains unchanged

---

And vise versa: whether an address book is renamed on the server, or on a client, the result is the same: a new name won't get propagated anywhere at all.
