`nonminimal_bool` suggestions missing required parenthesis

Summary

The nonminimal_bool suggestions are missing required parenthesis if they replace part of a larger expression. This causes cargo --fix to fail because the new code doesn't compile.

Reproducer

I tried this code:

fn main() {
    let x = 1usize;
    let b = false;
    println!("{}", !(x > 20) ^ b);
}

and then ran cargo --fix

I expected to see this happen:

The expression would be simplified to (x <= 20) ^ b

Instead, this happened:

Clippy tried to change the expression to x <= 20 ^ b which doesn't compile.

Output from Cargo:

after fixes were automatically applied the compiler reported errors within these files:

  * src/main.rs

This likely indicates a bug in either rustc or cargo itself,
and we would appreciate a bug report! You're likely to see 
a number of compiler warnings after this message which cargo
attempted to fix but failed. If you could open an issue at
https://github.com/rust-lang/rust/issues
quoting the full output of this command we'd be very appreciative!
Note that you may be able to make some more progress in the near-term
fixing code with the `--broken-code` flag

The following errors were reported:
error[E0277]: no implementation for `{integer} ^ bool`
