Preauth API error response does not contain conflicting device

When pre-authorizing a device using the API, if a matching device already exists, the 409 return code is returned. According to https://docs.mender.io/hosted/apis/enterprise/management-apis/device-authentication#responsesthe docs, it should also include the conflicting device. I used a curl command to test this and I do get the 409 return code but not the conflicting device info.
