`useless_conversion` eats the closing paren when removing `.into_iter()`

[ada4a]

Summary

When the receiver with the useless .into_iter() is enclosed in parens, the suggestion eats the closing paren

Reproducer

I tried this code:

#![warn(clippy::useless_conversion)]
#![allow(unused)]

fn main() {
    fn f(_: impl IntoIterator<Item = i32>){}
    f((vec![]).into_iter())
}

I expected to see this happen:

warning: explicit call to `.into_iter()` in function argument accepting `IntoIterator`
 --> src/main.rs:8:7
  |
6 |     f((vec![]).into_iter())
  |       ^^^^^^^^------------
  |              |
  |              help: consider removing the `.into_iter()`
  |

Instead, this happened:

warning: explicit call to `.into_iter()` in function argument accepting `IntoIterator`
 --> src/main.rs:8:7
  |
6 |     f((vec![]).into_iter())
  |       ^^^^^^^-------------
  |              |
  |              help: consider removing the `.into_iter()`
