fix: await insertion with try_expr during extract_function

Fixing #10333

This seems to be the wrong way to fix this, as extracting this

fn foo() -> i64 {
    loop {
        let n = 1;$0
        let k = async { 1 }.await;
        if k == 42 {
            break 3;
        }
        let m = k + 1;$0
        let h = 1 + m;
    }
}

also produces incorrect await order which wouldn't be fixed by this.

The proper fix I believe would be to add the .async expression to the call expression that is passed to let expr = handler.make_call_expr(call_expr).indent(indent); a few lines above instead. That should just fix these ordering issues.

This seems good?

Yep that looks right 👍
