Getting gosimple suggestion while running test script, so this PR is for fixing gosimple S1019 check. raft/node_test.go:456:40: should use make([]raftpb.Entry, 1) instead (S1019) raft/node_test.go:457:49: should use make([]raftpb.Entry, 1) instead (S1019) raft/node_test.go:458:43: should use make([]raftpb.Message, 1) instead (S1019) Refer https://github.com/dominikh/go-tools/blob/master/cmd/gosimple/README.md#checks for more information.
