GQL: datasets.byOwnerAndName should not return account prefixed alias in a single-tenant workspace

[andriidemus]

Describe the bug

We parse prefixed alias, as an alias from multi-tenant workspace.
For the consistency, it makes sense to make datasets.byOwnerAndName return unprefixed alias in case of singe-tenant workspace.

Here are several API calls examples in both single- and multi-tenant workspaces

Steps To Reproduce

1. Create single tenant workspace

kamu init

3. Start server

kamu system api-server --http-port 55667 --get-token
export KAMU_AUTH_TOKEN="<token>"

5. Create empty dataset

curl -s 'http://127.0.0.1:55667/graphql' \
  --header "Authorization: Bearer $KAMU_AUTH_TOKEN" \
  --data-raw '{"query": "mutation { datasets { createEmpty(datasetKind: ROOT, datasetAlias: \"empty-root-dataset\") { message ... on CreateDatasetResultSuccess { dataset { alias } } } } }"}'

7. Get dataset alias

curl -s 'http://127.0.0.1:55667/graphql' \
  --header "Authorization: Bearer $KAMU_AUTH_TOKEN" \
  --data-raw '{"query": "{ datasets { byOwnerAndName (accountName: \"kamu\", datasetName: \"empty-root-dataset\") {alias owner {accountName}} } }"}' \
  | jq .data.datasets.byOwnerAndName.alias

Current Behavior

Dataset alias prefixed with account name: "<account_name>/"

{
  "data": {
    "datasets": {
      "byOwnerAndName": {
        "alias": "kamu/empty-root-dataset",
      }
    }
  },
  "extensions": {}
}

Expected Behavior

Dataset alias format without account name prefix

{
  "data": {
    "datasets": {
      "byOwnerAndName": {
        "alias": "empty-root-dataset",
      }
    }
  },
  "extensions": {}
}

Offtop: @demusdev , you can run a GQL query using the following command:

kamu system api-server gql-query '{ apiVersion }'
