Update vue-i18n for bug fixes

Don't delete _i18n in beforeDestroy
(kazupon/vue-i18n#880):
Avoid that translations in long-running methods throw on
translations after destruction.

Allow component interpolation without root element
(kazupon/vue-i18n#878):
For fixed responsiveness of the mobile checkout cancel
button.
