      Description

      lastVote is initialized here. It is an error for the lastVote document to have a field other than "term" and "candidateIndex" but it has an "_id" field as well. This has gone unnoticed due to our lack of test coverage around lastVote (see SERVER-27569) and because we do not actually check the return status of lastVote's initialization.
