We create a snapshot (config only, but still), but do not assign it any
id. Because of that it is not loaded on start. We do want it to be
loaded though since the state of group0 will not be re-created from the
log on restart because the entries will have outdated id and will be
skipped. As a result in memory state machine state will not be restored.
This is not a problem now since schema state it restored outside of raft
code.
