[bug] vueRouterAdditionalEventData is not serializable

[dreitzner]

I discovered an issue with vueRouterAdditionalEventData.

Nuxt only allows serializable data to be in nuxt.$config, so vueRouterAdditionalEventData is discarded.

Is there any other way to add the additional data?

This would be a deal breaker on our implimentation, and we'd port the module manually into our codebase and extend as needed.
