Unless the total number of domains is too big, there is no need to
consume resources in neo-go.

If we had lots of domains in one zone, `dump-hashes` for all others
can miss some domains, because we need to restrict ourselves with _some_
number.
In this commit we use neo-go sessions by default, with a proper
failback to in-script iterator unwrapping.
