 Description   

If processReplSetRequestVotes is called when the node does not know its own member number (_selfIndex == -1), we will currently invariant when trying to access _selfConfig().  Instead, we should simply vote "no" with an appropriate message.

Closing as Won't Fix. This only affects removed nodes, and we have not seen this crash reported in the field. I'm not sure this is a good neweng ticket, since it could be hard to test.
