Test: ZenUnicastDiscoveryTests.testNormalClusterForming should start unicast hosts first 

The test starts a cluster with random nodes as unicast hosts but *doesn't* use min_master_nodes. If the unicast hosts are started last, nodes may elect themselves as master as they do not have mechanism yet to share information.
