Describe the Bug:
the integrationKey query returns an unexpected error and a SQL NoRows error is logged when an ID is provided that does not exist.

Steps to Reproduce:

1. Create an integration key
2. Save new integration key's ID
3. Delete said integration key
4. Go to /api/graphql/explore
5. Execute this query, substituting in the saved ID value

query{
  integrationKey(id:"<ID-VALUE-HERE>"){
    id
  }
}

Expected Response:

{
  "data": {
    "integrationKey": null
  }
}

Observed Response:

{
  "errors": [
    {
      "message": "unexpected error",
      "path": [
        "integrationKey"
      ]
    }
  ],
  "data": {
    "integrationKey": null
  }
}
