Cannot clone a URL in Node >= 10

[iambalaam]

The following code will run in node8, but break in node10 and node12.

const clone = require('clone');
const { URL } = require('url');
const url = new URL('https://example.com');

const url2 = clone(url);

It gives the following stacktrace

TypeError: Cannot set property 'flags' of undefined

this causes node-cache/node-cache#127 just leaving this here so we get a ref to track this issue in the original issue thread
