Description of problem:
When creating a SCAP Policy and selecting the parent hostgroup of multiple nested host-groups the 'policy:' does not apply to hosts that are members of the nested groups.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.Create 3 host groups

---|-------------|------------------|------------------|---------------------------------|------
ID | NAME        | TITLE            | OPERATING SYSTEM | ENVIRONMENT                     | MODEL
---|-------------|------------------|------------------|---------------------------------|------
1  | RHEL7Server | RHEL7Server      | RedHat 7.2       | KT_Example_ORG_Library_puppet_7 |      
5  | LNX         | RHEL7Server/LNX  |                  |                                 |      
4  | PROD        | RHEL7Server/PROD |                  |                                 |      
---|-------------|------------------|------------------|---------------------------------|------

2. Create an SCAP policy.
3. Assign the SCAP policy to the RHEL7Server host-group.

Actual results:
The policy does not apply correctly to a host in the nested groups LNX and PROD. The "policies:" become an unset array, instead of specifying policy ID and schedule. However the 'foreman_scap_client:' class is added.

classes:
  foreman_scap_client:
    policies: []
    port: '9090'
    server: sat61.lnx.example.com
parameters:
  puppetmaster: sat61.lnx.example.com
  hostgroup: RHEL7Server/LNX

Expected results:
The policy should apply correctly to hosts that are part of nested host-groups.
