Rewriting `r#try!` at root of chain generates bad code

[matthewhughes934]

Summary

Just recording something I ran into during my (ongoing) dive into chain formatting

I tried to format this code:

fn main() {
    let _ = r#try!(root)/* this is a comment*/.bar;
}

Expected behavior

It would be formatted to something like

fn main() {
    let _ = root? /* this is a comment*/
        .bar;
}

Actual behavior

It was formatted to invalid code:

fn main() {
    let _ = root? )/* this is a comment*/
        .bar;
}

Configuration

Only needs the use_try_shorthand option

Reproduction Steps

rustfmt --config use_try_shorthand=true ./file.rs
