presentationTexts is not set from presentationFields on instantiation.

### Description of the bug

`presentationTexts` is not set from `presentationFields` on instantiation.

### Steps To Reproduce

1. Create an app with `presentationFields` in `App/config/applicationmetadata.json`

```json
"presentationFields": [
{
"id": "År",
"path": "rapport.rapportering.aar.value",
"dataTypeId": "Finanstilsynet_KRT-1132Svindelrapportering_M"
}
],
```

2. Instantiate with a prefill that sets one of the `presentationFields`
3. See that the instance does not get `presentationValues` set on the instance
4. (open the instance, edit a field, and see that `presentationTexts` is set)

### Additional Information

_No response_

Start with App/config/applicationmetadata.json and trace instance instantiation when a prefill sets a presentationField. Compare that path with the edit flow, where presentationTexts is populated. Done means presentationTexts is set during instantiation for prefilled presentation fields, matching the behavior after editing.
