Description of problem:
Cannot create hostgroup associated with content source id=1 and LFE id=1 (Default Organization's Library) 

(x) Unable to save
The selected content source and lifecycle environment do not match

While other organizations' Libraries (id<>1) or other LFEs (id<>1) of the Default Organization are ok to match default content source (id=1)

This is regression against 6.5

Version-Release number of selected component (if applicable):
satellite-6.6.0-5.beta.el7sat.noarch
foreman-1.22.0-0.5.RC2.1.el7sat.noarch
katello-3.12.0-0.5.master.el7sat.noarch

How reproducible:
deterministic

Steps to Reproduce:
1.
 # hammer hostgroup create --name hg_library --lifecycle-environment-id 1 --content-source-id 1
Could not create the hostgroup:
  The selected content source and lifecycle environment do not match

while
 
# hammer hostgroup create --name hg_dev --lifecycle-environment-id 2 --content-source-id 1
Hostgroup created.


Actual results:
Default Organization's Library (with id=1) is problematic when creating hostgroup

Expected results:
Default Organization's Library works as other LFEs in regards to hostgroup creation
