Omschrijf het probleem / Describe the bug

Migrated form components contain incorrect "prefill" json:

  "prefill": {
    "plugin": null,
    "attribute": null,
    "identifierRole": "main"
  },

This causes crashes on import and copy of forms.

Updating the component changes null to "" and solves the copy issue

  "prefill": {
    "plugin": "",
    "attribute": "",
    "identifierRole": "main"
  },
