We were checking that, after a `visit`, we're redirected to the account
page, but, since we were already in the account page, the page doesn't
change at all. In order to be 100% that the request caused by the call
to `visit` has finished before checking the expectations, we're visiting
a different page first.
This way it's more clear what the user experience is during the process.
Note this did not result in flaky tests, since the tests continue by
clicking links, that are only present after the request has finished.
However, we're adding expectations so we don't have to think whether the
tests could be flaky and because this way we're also testing the user
experience; it would be strange for a user if they were redirected to a
page without a flash message.
