   @brkyvz if you look at the updated code, there is no v1 catalog call:
   1. It first resolves temp view, which is neither v1 or v2 path
   2. it determines the v2 catalog(can be `V2SessionCatalog`) and lookup the table from it
   3. if the v2 catalog is session catalog, return v1 relation if the table is `V1Table`
   
   step 3 is the only v1 part and it's easy to delete it when we get rid of v1 in the future.
