More tests for Parameters with source is a card. (#27667)

* FE gets `value_field` for `/api/table/card__id/query_metadata`
by search the fields from calling `/api/table/card__id/query_metadata`.
if a field has id is a number, then use `field_ref`, else use `id`.

This commit add tests for that behavior
