Fix "Missing queryFn" error when reloading with project openn

[somebody1234]

Pull Request Description

• Fix https://github.com/enso-org/cloud-v2/issues/1451
  • Fix "Missing queryFn" error due to
    • This is done by providing a default value to the query. A more ideal solution may be to use the full query with the queryFn, but this is not an option here as the full query for this query requires a lot more info, some of which we don't have.

Important Notes

• Test opening a top-level project and then refreshing
• Test opening a project in a nested directory and then refreshing (to make sure the query is not being executed just because the corresponding row is visible)
