test(e2e): expect a fresh account to reach onboarding, not billing

The registration spec asserted that a brand new account lands on /settings,
which was true only because registering left trialEndsAt empty. It is now
filled at signup, so the account has billing access and the dashboard lets it
through to the onboarding wizard. That redirect is the done condition of the
cardless trial, so the spec should hold it.
