Subject: [PATCH] minor: remove whitespaces in remove use-tree braces

Example
---
```rust
struct X; struct Y;
mod z {
    $0use super::{
        X, Y,
    };$0
    fn w() { let x = X; }
}
```

**Before this PR**

```rust
struct X; struct Y;
mod z {
    use super::
        X
    ;
    fn w() { let x = X; }
}
```

**After this PR**

```rust
struct X; struct Y;
mod z {
    use super::X;
    fn w() { let x = X(); }
}
```
