/**
 * When we removed scheduling of heartbeat in the AbstractLeader constructor we ended up with a situation where
 * if no follower responded to an initial AppendEntries heartbeats would not be sent to it. This test verifies
 * that regardless of whether followers respond or not we schedule heartbeats.
