Fixes #31364 - Properly import facts when unattended == false

The fact importer calls host.without_orchestration which is defined in
orchestration concern, however the concern is only included when
unattended == true. Users who have the setting set to false will not be
able to import facts as the fact importer will fail to find this method.
