Double describe table

[Fokko]

Expected behavior

We're seeing that dbt-trino is quite chatty (this is more a charasteristic of dbt, rather than dbt-trino). I noticed that when running an incremental model, we're seeing a double describe table:

describe                "sandbox"."dbt_trino"."locations_incremental"

Actual behavior

I would expect one describe table

Steps To Reproduce

This can be observed when running a incremental model:

{{ config(
  persist_docs={"relation": true, "columns": true},
  file_format="iceberg",
  materialized="incremental",
  unique_key='location_id',
  incremental_strategy='delete+insert',
) }}

SELECT *
FROM examples.nyc_taxi_locations
