KUDU-3641 fix flaky TestNewLeaderCantResolvePeers (take 2)
I noticed that even after [1] the TestNewLeaderCantResolvePeers was
still failing in about once in 60 runs [2], so I took a closer look.
It turns out StartElection() doesn't trigger a re-election if it
arriving at the current Raft leader. To address that, this patch
replaces StartElection() back with LeaderStepDown() but with new
target leader being the tablet replica at the third tablet server.
This is a follow-up to [1].
