Receipt is unable to show variables in appReceiver

[tina-ahm]

Description of the bug

When setting the appReceiver text resource with variables in an application the receipt does not fetch the variables, but rather shows the text resource as is. The expected behaviour is that the app receiver would be shown in the same manner as in the receipt shown when submitting a form.

Steps To Reproduce

1. Add a variable to the value the appReceiver text resource in an Altinn form. E.g.:

    {
      "id": "appReceiver",
      "value": "{0} Kommune",
      "variables": [
        {
          "key": "FlatData.KommuneNavn",
          "dataSource": "dataModel.DataModel",
          "defaultValue": " "
        }
      ]
    },

2. Submit the form and open the receipt from the Altinn inbox.
3. See that the appReceiver value differs from the two receipts. "Rana kommune" in the form receipt and "{0} Kommune" in the archive receipt.
