Use absolute path for hreflang attribute

[stophecom]

Google seems to recommend absolute links for alternative language links: https://support.google.com/webmasters/answer/189077?hl=en

E.g. <link rel="alternate" hreflang="en-gb" href="http://en-gb.example.com/page.html" />

Should be able to fix here: https://github.com/njam/nuxt-i18n-module/blob/e025a732377ee0d38b134775034b857510d0ca62/src/templates/plugin.js

We're using VueRouter to resolve hreflang URLs. There's a base option, but unfortunately it doesn't work with absolute URLs. Opened a ticket about it: vuejs/vue-router#2927

Unfortunately absolute URLs are out of scope for VueRouter, so we'll need to handle it here. I will look into it.

New option rootUrl is available in version 0.3.0
