Describe the bug

When using multiple lazy loaded files the original messages will be overwritten, but cannot be restored.

Imagine the following scenario:

en.json

{
  "welcome": "welcome!"
}

en-GB.json

{
  "welcome": "Test!"
}

nuxt.config.ts

...
i18n: {
    lazy: true,
    langDir: 'lang',
    locales: [
      {
        name: 'English (American)',
        locale: 'en-US',
        code: 'en-US',
        files: ['en.json'],
      },
      {
        name: 'English (British)',
        locale: 'en-GB',
        code: 'en-GB',
        files: ['en.json', 'en-GB.json'],
      },
    ],
  },
...

Originally, when first navigating to the page the message will read "welcome!", then when switching to en-GB it will switch to "Test!" (So far so good). However, when switching back to en-US the text will still read "Test!". When force reloading the page it will turn back to "welcome!".

Expected behavior

When swapping back to a locale that was previously overwritten/inherited the original messages should be restored.
