client-oauth2 hasn't had a new release in about three years. Should probably look at replacing it at some point.

The one in nuxt-app:

It's safe to ignore (nuxt/nuxt#9284).

Also got rid of a bunch of warnings about unmet/incorrect dependencies (made explicit some previously only implicit stuff).

Removed modernizr because it seemed like we hadn't used it in a long time.
