This commit improves the testing around cases where a (pre-)candidate wins an election without having voted for themselves. This was already tested by TestCandidateDeliversPreCandidateSelfVoteAfterBecomingCandidate, but this commit expands the testing to handle three related cases and to mirror the existing TestCandidateSelfVoteAfterLostElection test.

Convert these to use require package while here?

Why? Is this because the leader doesn't count votes in general (it doesn't need to already)? Or there is just special handling of leader self-vote?
Might be good to clarify the comment.

The r.msgsAfterAppend has already been reset to nil when getting the steps2 (line 1888)
