Enhancements in routing

[reyraa]

Expected behaviour

• After logging in, clicking back button should not #navigate to login page.
• Reloading should sign out the user and redirect to login page
• Fix unit tests.

Actual behaviour

• Currently clicking on back button navigates to login page, even if already logged in.
• reloading breaks the app ( if using # in route structure helps fixing this, it's fine)
• We've skipped existing route tests since navigating directly to those routes is not possible. we need to navigate to Login, and call onLoginSubmission with proper inputs, or find an approach to store active peer and account info on the store.

Steps to reproduce

Run e2e tests for the skipped test in src/components/app.js
