Account_name Rest API call on Contacts module

Hi,

We observed there was an additional rest api call((/rest/v11_16/Contacts/<SugarCRMUUIDForRelatedPatronID>?erased_fields=true&fields=account_name ) added on contacts module load after SugarCRM Upgrade from v8.0.0 Ent to v12.0.2 which we didn't seen on Sugar 8 Instance and on our observation we found there is an field named "denorm_account_name"added on contacts module vardef path but on validation the denormalization settings are not enabled on instance.

1. "Rebuild Denormalized Team Security Data" Scheduler is "inactive"

2. Denormalization settings are not configured in config_override.php file.

We didn't require this account_name rest api on contacts module, so if anyone have idea on removing this rest API call please share.

Thanks in advance.
