@babel/polyfill pt2 electric boogaloo

When trying to use this library in typescript project like so:

import EthRegistry from 'eth-registry';

const registry = new EthRegistry(); // use default provider

I get the following error:

./node_modules/idempotent-babel-polyfill/node_modules/@babel/polyfill/lib/noConflict.js
Module not found: Can't resolve 'core-js/modules/web.dom-collections.iterator' in '/Users/cory.dickson/GitHub/eth-registry-frontend/node_modules/idempotent-babel-polyfill/node_modules/@babel/polyfill/lib'

This seems to be related #3 and #2 but should be fixed by switching over to @babel/polyfill>=7.4.0. I've tried other workarounds to no avail, such as bringing an older version of core-js in the entry of my application or symlinking the paths(too hacky).

.babelrc

{
  "presets": [
    "@babel/env",
    {
      "useBuiltIns": "usage",
      "corejs": 3
    }
    "@babel/preset-typescript",
  ],
  "plugins": [
    "@babel/proposal-class-properties",
    "@babel/proposal-object-rest-spread"
  ]
}

Maybe we can use the same polyfill version in walletconnect as well @pedrouid?
