When a leader learns of a newer term and steps down, it should discard current_leader. Otherwise, a client request may be rejected with RAFT_ERR_NOT_LEADER and a hint pointing to this replica itself! For simplicity, this patche follows the Raft paper to discard current_leader whenever current_term changes. And, when receiving an AE with an up-to-date term, a server always updates current_leader, as this information is absolute, even if the previous entry doesn't match. This patch also fixes a test that has previously been failing due to incorrect node IDs. Signed-off-by:
