Queue static table exports should use object id when working with exported queue

In static exports we take a snapshot lock on the exported queue. As per the [docs](https://ytsaurus.tech/docs/en/user-guide/storage/transactions#locking_mode), you should use the object id returned by the lock command when working with a snapshot of an object. We [use](https://github.com/ytsaurus/ytsaurus/blob/main/yt/yt/server/queue_agent/queue_static_table_exporter.cpp#L339) the path instead (probably in other places as well). Let's fix this.
