Describe the Bug

When I query a collection with a single file field I can no longer rename the field.

GraphQL returns.

Cannot destructure property 'type' of 'field' as it is undefined.

To Reproduce

Create a new collection test with a default id and add one "Single File" file field. You'd end up with something like this.

CREATE TABLE `test` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `file` char(36) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `test_file_foreign` (`file`),
  CONSTRAINT `test_file_foreign` FOREIGN KEY (`file`) REFERENCES `directus_files` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

You could add an item to the collection for easier debugging, but it isn't necessary to reproduce the issue.

Query the file field with permissions (or set public read access to the collection and directus_files).

Without renamed fields it works fine 👍

{
  test {
    file { id }
  }
}

With a renamed field it returns an error ⚠️

{
  test {
    renamedField: file { id }
  }
}

{
  "errors": [
    {
      "message": "Cannot destructure property 'type' of 'field' as it is undefined.",
      "locations": [
        {
          "line": 1,
          "column": 17
        }
      ],
      "path": [
        "test"
      ]
    }
  ],
  "data": {
    "test": null
  }
}

This was not an issue in rc-93. The issue is producible in both rc-94 and rc-95.

I dug into the code and commits between those versions without success. If I have to guess I'd say it came with the Insight module changes.
