Consider adding `clippy::has_significant_drop` attribute to `Object`

[silverpill]

Documentation: https://doc.rust-lang.org/clippy/attribs.html#clippyhas_significant_drop

If significant_drop_in_scrutinee lint is enabled, a warning would be generated about an un-intuitive behavior of temporaries in match scrutinees that might lead to deadlocks:

match make_query(&pool.get().await.unwrap()) {
    Ok(_) => {
        // Connection still not returned to the pool!
    }
    ...
};
// Connection is only released here
