Description

Let's say I have a situation like this:

use foo::bar::{baz, quxx};
               ^~~ unused import

If I use the "remove unused import" assist, I end up with

use foo::bar::{quux};
              ^~~~~^ remove unnecessary braces

So I have to trigger another assist immediately after removing the unused import, which is kinda silly.

It would be great if the unused import assist was smart enough to remove unnecessary braces here.

No file or test is named. Start by reproducing the Rust example and tracing the unused-import assist entry point; done means one assist removes the unused import and also removes braces when exactly one import remains in the group.
