TypeError: URLParser is not a constructor in Node 6.12.2

[gnicolae14]

The normalization function (version 3.1.0) does not work with node 6.12.2

The problem seems to be at the line:

const URLParser = typeof URL === 'undefined' ? require('url').URL : URL;

My guess is that it needs to be:

const URLParser = typeof URL === 'undefined' ? require('url').parse : URL;

Here's a sample how to reproduce the issues:

$ nvm install 6.12.2

$ nvm exec 6.12.2 node
Running node v6.12.2 (npm v3.10.10)

> norm = require('normalize-url')
[Function]

> norm('http://example.com/some/path')

You need the latest Node.js 6 version (Node.js 6.14).
