i18n is managed by root component:
* ok for person and household implementation (=> they use Address root component)
* but must be imported in vue i18n file if called from another component
submitAddress is emit to parent, it allow to control final action:
* casting final submitNewAddress with POST requests (for person or household entity);
* or dispatching changes from store, casting only payload to be used.
remove and simplify some options: backurl is always used with person/household,
and never if called from another vue component.
