INTLY-4959 - fix sorting service crashes on login on os4

[KevFan]

Motivation

On OS4, login is broken due to the object returned when calling getServiceSortOrder() does not contain a spec object causing an undefined error and crashing the webapp on login

Jira:

• https://issues.redhat.com/browse/INTLY-4959

What

• If cluster is OS4, get the service name from svc.name instead of svc.spec.clusterServiceClassExternalName

Verification Steps

1. Install integreatly on a OS4 cluster
2. Scale down the web app operator to prevent it reconciling back to specified image
   • oc edit deployment tutorial-web-app-operator -n rhmi-solution-explorer
3. Change image to quay.io/kevfan/tutorial-web-app:2.21.1 on tutoiral web app deployment config
   • oc edit deploymentconfig tutorial-web-app -n rhmi-solution-explorer
4. Run the ./scripts/setup-htpass-idp.sh to create sample users
5. Visit solution explorer and ensure you can sign in and sign out without errors with the created users Note: There is an known issue where logging out using kubeadmin would sign the user back in. Just testing the users created from the script should be fine
