Steps to Reproduce

1. Create a new tenant.
2. Get an access token for that tenant with an application with internal_organization_update scope.
3. Use the PATCH API with the root org ID to change the name:

curl --location --request PATCH 'https://localhost:9443/t/abc.com/api/server/v1/organizations/69a7e2df-8205-4196-8b4a-f363fa4e0ec4' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'Authorization: Bearer 9c02ec4c-5731-3e12-b13d-d91dbd1696b3' \
--data '[
  {
    "operation": "REPLACE",
    "path": "/name",
    "value": "ABCDEFG Builders"
  }
]'

This is because the parent ID returns null for root organizations in validateOrgNameUniqueness method.
