It's better to fix test logic:
Here: https://github.com/openstack/tempest/blob/master/tempest/api/identity/admin/v2/test_tenant_negative.py#L103

Token gets deleted. Using Fernet token with revocation tree disabled this action has no effect:
token is issued and keystone has no information of it; on validation keystone just checks if the user has roles in project/tenant - and if roles are intact, the token is still valid.

I suggest just removing token issue and deletion as test is named "create_tenant without token" and not "create_tenant with deleted token"
