fix(tests): correct usage of column in delete statement for Guild model

- Updated the delete statement in the test for model relationships to use `column("id")` instead of directly referencing `Guild.id`, ensuring proper execution of the SQL delete operation.
- This change enhances the clarity and correctness of the test implementation.
