Comment 0 for bug 1541539

Found on CI:
https://product-ci.infra.mirantis.net/view/8.0_swarm/job/8.0.system_test.ubuntu.backup_restore_master/126/console

Test steps:
            1. Revert snapshot "deploy_ha_one_controller_backup_restore"
            2. Backup master
            3. Check backup
            4. Run OSTF
            5. Add 1 node with compute role
            6. Restore master
            7. Check restore
            8. Run OSTF

Initial snapshot includes two nodes. So after snapshot's restoring there should be 2 nodes after step 6. But we have 3 nodes: 1 is pending addition.
