Fix: react-router 5.1+ not forwarding props to wrapped component

[icd2k3]

Fixes a small issue for those using react-router 5.1. Props were not being forwarded to the wrapped component. For example:

// MyWrapper.js
<Breadcrumbs someOtherProp="hello" />

// Breadcrumbs.js
const PureBreadcrumbs = ({ someOtherProp }) => <span>{someOtherProp}</span> // UNDEFINED!
export default withBreadcrumbs()(PureBreadcrumbs)

Smaller fixes include:

• bumping some dev dependencies
• fixing some TS errors
• adding a test for pass through props
