Rustfmt puts single-line comment after wrong import when reordering imports

before rustfmt:
```rust
pub use views::*;
pub use foo::bar; // re-export for frontend
```
after (with import reordering enabled):
```rust
pub use foo::bar;
pub use views::*; // re-export for frontend
```
The comment is at the wrong import now. It should not just reorder the imports but also their comments with them!
