"Remove all the unused imports" assist removes used derive macros

For the following code:

use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize)]
struct MyStruct {
    field: i32,
}

fn main() {
    println!("Hello, world!");
}

The "remove all the unused imports" assist is suggested for the use block.
If applied, it will remove the imports, even though they are being used by a derive macro.

Reproduce the issue with the serde example in the report and invoke the “remove all the unused imports” assist on its use block. Trace the assist's unused-import handling and verify that imports referenced only by derive macros are retained while genuinely unused imports are removed.
