When a project is transferred, GraphQL returns empty results when fetching by old namespace and iid.
There was a similar feature request implemented for API https://gitlab.com/gitlab-org/gitlab/-/issues/30013
Feature flag https://gitlab.com/gitlab-org/gitlab/-/issues/421992
### Proposal
When the work item is fetched via GraphQL, Gitlab handles any redirects:
* [Related GraphQL code](https://gitlab.com/gitlab-org/gitlab/blob/master/lib/gitlab/graphql/loaders/full_path_model_loader.rb?ref_type=heads#L17-17)
* find_by_full_path(id, follow_redirects: true) in [API response](https://gitlab.com/gitlab-org/gitlab/blob/3a7857cc65bf736d198bdcb43cbf57da01f78330/lib/api/helpers.rb#L161)
