manual_ok_err automatic fix doesn't add {} when after else

[Sliman4]

Summary

Broken code after applying automatic fix

Reproducer

I tried this code:

fn main() {
    let n = if false {
        None
    } else if let Ok(n) = "1".parse::<u8>() {
        Some(n)
    } else {
        None
    };
}

with --fix

I expected to see this happen:

fn main() {
    let n = if false {
        None
    } else {
        "1".parse::<u8>().ok()
    };
}

Instead, this happened:

fn main() {
    let n = if false {
        None
    } else "1".parse::<u8>().ok();
}
