I found that `react-router.js` test is broken with latest version of `history` (currently @ `5.0.0`):

```sh
$ yarn upgrade history@latest

Esegui `yarn test` e ispeziona `src/__tests__/react-router.js`, in particolare il caso di rendering/navigazione dell'app completa che non riesce dopo l'aggiornamento di `history` alla versione 5.0.0. Traccia il comportamento di navigazione che fallisce e verifica che l'intera suite di test passi con la correzione di compatibilità prevista.
