Sometimes callback would never be called

Line 50 in 6ae3454

return Promise.reject(new TypeError('expected the first argument to be a string'));

This error should be passed to the callback.

Can you provide some example code with a case where this is causing a bug?

If so, a PR with a fix for the bug will be welcome.

Assumes the user is using "async callback" API:

const deleteEmpty = require("delete-empty");

const path = undefined; // assumes the input is wrong

const onDone = (err, result) => console.log("finished", err, result);

try {
  deleteEmpty(path, onDone);
} catch (err) {
  console.log("err", err);
}

You will get an unhandled promise. REPL
