Not able to adopt the new notary actor API

[notimetoname]

Context

Trying to update notary API in the neofs-node and can't receive new notary requests via WSClient subscription mechanism. I do not change any subscription code, do not change any contracts code, do not update neo-go version, just a deprecated API -> new API adoption. Signers of a notary requests are 1. Proxy contract, 2. Alphabet multi-signature, 3. request invoker (SN in practice).

No errors are returned after Notarize call, and no errors found in neo-go logs. Also tried to remove any filters in the subscription (to receive every new notary request) and still no desired requests.

SN logs after Notarize:

4 requests from 4 nodes, no errors.

At the same time, sending notary requests works just fine: epochs do tick.

NOTE: I DO consider that I could have adopted the new API wrong. If it is my fault, I would like to ask to expand comments/docs/etc cause I have not solved my problem and do not know how to localize the error without any additional help now.

Steps to reproduce:

1. Checkout demo neofs-node (that is the current master with demo commit only);
2. Build necessary images: make bin/neofs-node image-dirty-storage bin/neofs-ir image-dirty-ir i expect it to be 0.35.0-96-g5bbfb13b tagged (depending on your local tags state);
3. Checkout demo neofs-devenv (i expect a reader to be familiar with it and be able to run it (no macOS, filled /etc/hosts, etc));
4. Run devenv: make up/basic;
5. See an empty netmap (it means no addPeer notary requests have been caught by the Alphabet nodes);

▶ neofs-cli netmap snapshot -g -r s01.neofs.devenv:8080     
Epoch: 7

6. Have fun.

The reason is that Notary actor do not add "dummy" witness for multisignature account if no witness can be provided. And the old neofs-node code does (it was the old way of submitting notary requests). See the 7-th step of the documentation, the right way to construct incomplete multisignature witness with no known signatures is to leave it empty (as the Notary actor does).

So the problem is on neofs side.
