Expected behavior

exturl should return the correct URL.

Actual behavior

When with hexo-renderer-markdown-it, exturl replaces & in the URL with &.

When exturl is turned off, URL does not change.

If hexo-renderer-markdown-it is not installed, the correct URL is showed.

Steps to reproduce the behavior

I ran this on Arch Linux.

sudo npm install -g hexo-cli
mkdir hexo && cd hexo
hexo init
git clone https://github.com/next-theme/hexo-theme-next themes/next
sed -i "s/theme: landscape/theme: next/" _config.yml
echo -e "\ntheme_config:\n  exturl: true" >> _config.yml
echo '[DuckDuckGo](https://duckduckgo.com/?q=markdown+syntax&t=hy&va=g)' >> source/_posts/hello-world.md
npm uninstall hexo-renderer-marked --save
npm install hexo-renderer-markdown-it --save
npm update
hexo server

I can upload my repo page, but it uses a different config. (but shows the same symptom)
