[6.16.z] remove user to prevent ForeignKeyViolation

[Satellite-QE]

Cherrypick of PR: #17024

Problem -
When creating another user with a specific role and adding resources in the filter with the 'view_facts' permission, an error occurred ('PG::ForeignKeyViolation: ERROR: update or delete on table "hosts" violates foreign key constraint "fact_values_host_id_fk" on table "fact_values"') during the teardown process while deleting the host. This happened because a user with only view permissions existed for the host and making it impossible to update or delete the user associated with the fact.

Solution -
To prevent this error, the user was removed before the teardown process.
