FuelUI unpredictable behavior adding Operating system + multi role

[okosse]

In FuelUI adding the role of the Operating system and the creation on its basis multirole leads to unpredictable results: roles are not added or added otherwise.
Steps to reproduce: create an environment. The type of hypervisor, network, etc. is not the value. Determine for one node the role of the Operating system and assign other nodes any role. Now, if you combine multirole, will fail.

Please provide any screenshot or additional specific steps to reproduce. Can't reproduce the issue on master (fake-ui).

I've reproduced this bug again.

Steps to reproduce:
1. deploy lab using iso : 6.1 build 92
2. create env with parameters:
-OS: any (as example I uses Ubuntu)
-hypervisor: vcenter
-settings for vcenter : any
-networking setup: default
-storage backends: default
-additional services: default

3. click on create nodes button and add:
 - 1 node with role : cinder
 - 1 node with role: operating system
4. then select node with role 'Cinder' and add to this node role : 'OS'
    and click 'Apply changes button'
 expected result:
                 1 node with role 'Cinder-Based OS' and 1 node with role Based OS
 actual result:
                 nothing is changed
                 instead role 'Cinder-Based OS' we still have :
                 - 1 node with role : cinder
                 - 1 node with role: operating system
5. let's try another scenario:
   so we still have:
 - 1 node with role : cinder
 - 1 node with role: operating system
   let's try to apply one more role to node with 'operating system' role
6. so select node with role 'operating system' and add to this node role : 'contoller'
    and click 'Apply changes button'.

 expected result: 1 node with role 'Controller-Based OS' and 1 node with role Cinder
 actual result: we got 1 node with role 'Cinder-Based OS' and 'Based OS'

--------------------
Conclusion: mechanism of assigning new roles to the existing nodes which already have roles, works incorrectly.
