fix: logging-in should not navigate to auth/logout (#407)

* When the logout button is clicked in development mode, the app navigates
  to /auth/logout, which in turn sets up a redirect_uri to the root uri.
  However, redirecting preserves the logout uri as the final target uri
  and ends up displaying a blank page.

* If the current uri is /auth/logout when creating a login then reset it
  back to / ensuring that the blank page is never displayed and the app
  correctly logs in.
