Test: fix testStaleMasterNotHijackingMajority by waiting for the old master node to step down. 

It may take some time for the old master node to step down anf for it to rejoin and that all nodes have it in the nodes list.
By waiting for the old master node to have stepped down, we can again rely on assertDiscoveryCompleted() to make sure that it has joined.
