Merge branch 'fix-config-baseurl' into 'master'

Fixes baseurl

## Why

Blog posts urls aren't correct:

Example, newest post url: https://pages.gitlab.io/hugo/hugo/posts/newest/ (`/hugo/` is repeating itself)

Correct path: https://pages.gitlab.io/hugo/posts/newest/

## How to fix this

Baseurl (current, not working): `"/hugo"`

Baseurl (correct): `"https://pages.gitlab.io/hugo/"`

## Working example

Config: https://gitlab.com/virtua-tests/hugo/blob/master/config.toml

Website: https://virtua-tests.gitlab.io/hugo/

Posts:

https://virtua-tests.gitlab.io/hugo/posts/newest/

https://virtua-tests.gitlab.io/hugo/posts/middle/

https://virtua-tests.gitlab.io/hugo/posts/oldest/
