Restart node test (#3459) (#3465)

Browse Source 
* Restart node test (#3459)

* Add test to local_cluster for restarting a node

* fix so that we don't hit end of epoch - leader not found before trying to transfer

* Do not look for confirmations, b/c nobody is voting on empty transmissions in this single node test
