returnDatasetFieldTypes=true not working on non-root collection inheriting "citation" from root

[pdurbin]

To reproduce:

• Create a collection with an alias/identifier of "testCollection"
• Publish it
• Go to the following URL: http://localhost:8080/api/dataverses/testCollection/metadatablocks?onlyDisplayedOnCreate=true&returnDatasetFieldTypes=true

Expected results: "fields" should be populated with title, etc. from the citation block.

Actual results: "fields" is an empty object

{
  "status": "OK",
  "data": [
    {
      "id": 1,
      "name": "citation",
      "displayName": "Citation Metadata",
      "displayOnCreate": true,
      "fields": {}
    }
  ]
}
