node: `util.promisify(fs.exists)` always rejects

[kt3k]

util.promisify works differently in node and deno_std/node when the fs.exists is passed to it.

The following code prints Error!!!\ntrue (assuming README.md exists in current dir)

import { promisify } from "https://deno.land/std@0.146.0/node/util.ts";
import { exists } from "https://deno.land/std@0.146.0/node/fs.ts";
const pExists = promisify(exists);
try {
  const result = await pExists("README.md")
  console.log("exists", result);
} catch(e) {
  console.log("Error!!!");
  console.log(e)
}

On the othe hand, the following prints Success\ntrue with node.js:

const util = require("util");
const fs = require("fs");
const pExists = util.promisify(fs.exists);
pExists("README.md").then(x => {
  console.log("Success");
  console.log(x)
}).catch((e) => {
  console.log("Error!!!");
  console.log(e)
})
