Hypervisors tasks showing warning as result - undefined method `[]' for nil:NilClass

Issue

• After configuring virt-who via Satellite webui (virt-who configuration helper) for access to multiple virtualization environments, we are able to see errors on production.log and on tasks (some tasks with warning as Result). As a consequence, the Guest information will not be updated on the Satellite side causing issues related to subscription process/entitlement.

• Task fails with error
