 Description   

In replsettest.js, if a transient network error occurs during _callIsMaster(), the node that failed to connect will not get added to _liveNodes. When we stop a replica set and do our auth checks, it is possible to pass _liveNodes into asCluster() without the correct number of live nodes.

We should make sure that _liveNodes isn't missing a node before we send it through asCluster().
