Steps to replicate the issue (include links if applicable):

• Define and create a Cargo table that uses a hierarchy field, e.g.

{{#cargo_declare:_table=Opinions
|Species=String (hierarchy;allowed values=*Human
*Orc
*Halfling
*Elf
*Dwarf
*Undead
**Skeleton
**Phantom
**Zombie
**Vampire
)
|Opinion=String
}}

• Recreate data into a replacement table and switch in the replacement table

What happens?:
cargo_tables.field_helper_tables still refers to the hierarchy table names as they were during the replacement process, e.g. Opinions__NEXT__Species__hierarchy. If the table is then deleted, these hierarchy tables get left behind.

What should have happened instead?:
Hierarchy table names should be renamed inside cargo_tables too when the replacement table is switched in, like list tables already are.
