Define language order when infusing if extract used --split

[mrleblanc101]

Currently, all my FR string are first and EN are second.
When I extract this is fine.
When I infuse, the string are inserted by alphabetical order of lang, which mean EN first.
This and #246 mean all my lines are changed if i were to commit the updated translation.

Here are my commands:

"i18n:extract": "vue-i18n-locale-message squeeze --target src --split --output messages",
"i18n:infuse": "vue-i18n-locale-message infuse --target src --locales messages --match '^([\\w-]*)\\.json$' -p=.prettierrc"

I have about 3000 string in 200-300 components so this is a big issue for me.
