A few lines of code were left out when backporting #10515 into Katello 4.8 and 4.7. See the redmine issue for details

Considerations taken when implementing this change?

What are the testing steps for this pull request?

Check out the branch
bundle update
Register a host in a non-SCA org
Sync some custom content, but do not attach a subscription
Turn on SCA in the org
Look for the output of the Actions::Katello::Organization::SimpleContentAccess::PrepareContentOverrides subtask in the Dynflow console under "Enable Simple Content Access"

Before:

# Actions::Katello::Organization::SimpleContentAccess::PrepareContentOverrides (success) [ 0.07s / 0.07s ]
---
migrator_result:
result: Finished creating overrides in non-SCA orgs; 2 errors
errors: 2
host_errors: Hosts - 1 error creating disabled overrides for unsubscribed content;
see log messages above
ak_errors: Activation keys - 1 error creating disabled overrides for unsubscribed
content; see log messages above

After:

migrator_result:
  result: Finished creating overrides in non-SCA orgs; no errors
  errors: 0
  success_message: Organization may now be switched to Simple Content Access mode without any change in access to content.

Also, in Repository Sets for the host, you'll see a disabled override for your custom repo.

ACK, works tested on a production katello 4.8 install

• Followed testing steps and I can see the task after flipping SCA on in the Partha org
  

Will test on 4.7 next for the other pr

Code looks fine as well
