The iterator does not handle the case where there are no records in
the box.info.replication table in case of deleting old records,
for examle:
```
- 1:
id: 1
uuid: 77f30d9a-d344-4f7a-a18c-578fb5ec2540
lsn: 4
name: null
3:
id: 3
uuid: 0ce528ca-ea35-42be-96b5-35ba610f9a3e
lsn: 0
downstream:
status: follow
idle: 0.14953243732452
vclock: {1: 4}
lag: 0.0015106201171875
name: null
```
It leads to the error and unable to start queue:
```
queue_state.lua:50: attempt to index a nil value
```
