REST put api/index.php/contacts/<id> fails to update ref_ext field

[a-schild]

Bug

When using the put method on a contact to update the ref_ext property, this field is not updated

Environment

• Version: 13.0.2
• OS: Debian 10
• Web server: Apache2
• PHP: 7.4
• Database: MariaDB
• URL(s): put api/index.php/contacts/

Expected and actual behavior

The new value of the ref_ext field should be stored in the database and also returned in the response.

Steps to reproduce the behavior

curl -X PUT --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'DOLAPIKEY: xxxxxxxx' -d '{
"ref_ext": "Updated"
}' 'http://192.168.189.6/api/index.php/contacts/29936'

Response:

{
  "ref": "29936",
  "ref_ext": "",
....
}

Doing the same on thirdparties, just works fine and the ref_ext is updated in the thirdparty
