FIX make sure conversation IDs are not sent out as UUIDs to the database

[ayeganov]

Description

When interacting with PostgreSQL I ran into a problem of db exceptions because conversation ids were being created as uuids and eventually those values were being sent to memory_interface functions where the conversation of uuid to str was not happening and the DB was raising exceptions of incompatible types. Converting those ids to str type resolved this problem.

@ayeganov thanks for the fix! Could you create a test case where you provide IDs of various input types and then assert that what's passed in the (mocked) DB call is actually string? If you want me to elaborate or point you to examples please lmk!
