I add check for status to prevent multiple assignment described in 

    TODO(mihgen): should we change status only once?

here: https://github.com/Mirantis/fuelweb/pull/1255/files#L1L151

Another way simplify condition or remove it and do nothing.

```ruby
if target_uids.include?(n['uid']) && n['status']
```

I propose to simplify the condition as above. What do you think?
