Static session does not expire in the next epoch

[vvarg229]

The tests "Validate static session which expires at next epoch" and "Validate static session that is valid" do not work because the session token has not expired.

If I understand correctly, after the second tick of the epoch:

1. First tick:

self.tick_epoch()
        head_object(
            user_wallet.path,
            container,
            object_id,
            self.shell,
            self.cluster.default_rpc_endpoint,
            session=token_start_at_next_epoch,
        )

2. Second tick:
   self.tick_epoch()

we expect to get an error "session token has expired", but it's not happening:

Expected Behavior

We should get a message that the session token has expired.

Current Behavior

Steps to Reproduce (for bugs)

Run automated system tests.

Context

I'm trying to get consistently green tests.

Regression

Yes

[vvarg229]

If it's really a bug, then the tests nspcc-dev/neofs-testcases#535 was falling correctly.

@vvarg229 IIUC we set exp to epoch N (99), and send request at epoch N. Currently, resulting behavior is expected and corresponds to the implementation: request is valid at epoch N and invalid starting from N+1

we have an open issue in protocol related to this topic nspcc-dev/neofs-api#253

if I didn't mess up the epoch numbers, i suggest to rework the test:

• PASS at epoch exp
• FAIL at epoch exp+1
