Undefined translation with default installation due to error in loadLocaleMessages function

[yuchiko]

Module versions

• Vue CLI: @vue/cli 4.3.1
• vue-cli-plugin-i18n: 2.0.1
• vue version: 2.6.11

To Reproduce
Steps to reproduce the behavior:

1. Create new vue application with vue-cli
2. Add i18n with vue-cli command vue add i18n
3. For all steps due the installation press Enter (en language)
4. Try to use translation in any component by using $t('message')
5. Note the issue that it shows a key only without translation

Expected behavior
It should show a translation from locales/en.json file

Additional context
I fixed this bug by removing .default in loadLocaleMessages function

So now I have:
messages[locale] = locales(key) instead of messages[locale] = locales(key).default

Because after testing I've assume that it returns undefined with .default

release done!
