The clients-registrations API doesn't return secret anymore on RH-SSO 7.5

Issue

I was able to register a new service account using 'single' POST on /clients-registrations API. I got in response the new client representation and the secret.

But with the new version of RHSSO (7.5), I'm not able anymore to register a new service account using 'single' POST on /clients-registrations API because I need to perform an additional PUT on /clients-registrations API for the secret to being generated and then an additional GET on /clients-registrations API to finally get the secret in client representation response.

To reproduce follow the steps:

Write a data.json with:

{
"clientId":"my_client",
"fullScopeAllowed":false,
"bearerOnly":false,
"consentRequired": false,
"standardFlowEnabled":false,
"implicitFlowEnabled":false,
"directAccessGrantsEnabled":false,
"serviceAccountsEnabled":true,
"publicClient":false
}

• RHSSO 7.2

curl -H "Authorization: Bearer $access_token" -H "Content-Type: application/json" --data @data.json -X POST "https://localhost:8080/auth/realms/master/clients-registrations/default/"  

Result: client representation + secret in response

• RHSS0 7.5+

curl -H "Authorization: Bearer $access_token" -H "Content-Type: application/json" --data @data.json -X POST "https://localhost:8080/auth/realms/master/clients-registrations/default/"

Result: client representation only in response (no secret)

curl -H "Authorization: Bearer $access_token" -H "Content-Type: application/json" --data @data.json -X PUT "https://localhost:8080/auth/realms/master/clients-registrations/default/my_client"

Result: client representation only in response (no secret, but on RHSSO side secret has been generated)

curl -H "Authorization: Bearer $access_token" -X GET "https://localhost:8080/auth/realms/master/clients-registrations/default/my_client

Result: client representation + secret in response
