When deleting a contact, it still remains in the acpeerstates table

[missytake]

• Operating System (Linux/Mac/Windows/iOS/Android): Debian 12
• Core Version: 1.158.0
• Client Version: deltachat-rpc-client 1.158.0

Expected behavior

Bots have to be able to forget about a contact for privacy reasons. After a contact is removed from all chats, it can be deleted. I'd expect it to be deleted from all database tables.

Actual behavior

The email address and the public key remain in the acpeerstates table, and maybe also in other database tables (I don't have a good way to check all tables, is there a command for that?)

Steps to reproduce the problem

1. Create new Alice + Bob profiles
2. Send a message from Bob to Alice
3. In Alice's account, delete the 1:1 chat with Bob
4. In Alice's account the Bob's contact
5. In an sqlitebrowser or similar software, run select * from acpeerstates; in Alice's dc.db file
