The SBL bdrige endpoint parties/byssnorgnumber doesn't include first or middle name

[SandGrainOne]

Description of the bug

During testing of the new partyComponentOption parameter on the nameslookup endpoint we were unable to find any cases where first name were included. The only name component being populated is the last name.

Analysing it a bit further show us that the issue is probably originating in SBL. The first and middle name components aren't being populated.

Steps To Reproduce

Tested i AT22:
POST https://platform.at22.altinn.cloud/register/api/v1/parties/nameslookup?partyComponentOption=person-name

        {
            "ssn": "07855499058"
        }
    ]
