fix: billing address overwrites shipping address when copy flag is set (#510)

* fix(theme): don't redirect with empty cart on thank-you step during the checkout

* fix(theme): fix on billing step when address for shipping and billing are the same

When addresses are the same, hide the form on the billing-step so users can't fill in a new address

* chore(theme): added missing translations
