Fuel cli breaks a connection when start deploy with node deletion

[Stanislaw Bogatkin]

Fuel 9.0, current master (have caught this on custom #1308 ISO).

Steps:
1. Create env, add 1 controller, 2 compute. Start deploy.
2. After successful deployment, delete one node (from UI, for example)
3. Run `fuel deploy-changes --env-id <real id>` from master node

Expected:
1. There will be a cli which will show a progress of redeployment

Real result:
2. After node deletion and resetting progress broke in a half of a process with error:

[root@nailgun modules]# fuel deploy-changes --env-id 1

... <omitted>
There was real progress showed for some time - couple of minutes or so.
... <omitted>

404 Client Error: Not Found for url: http://10.109.0.2:8000/api/v1/nodes/5/ (Node not found)
[root@nailgun modules]#

Node 5 there is the node which was deleted.

Actual redeployment process didn't stopped, though
