Mincer assetPath helper ignore mount-path flag

[zanonnicola]

Hi team,

I was using <%= asset_path('resource') %> in my css file to retrieve some resources (web fonts in my case) and I noticed that after running shunter-build script all my webfonts where being served from the root www.domain.com/public/resources/web-font.woff instead of from the path declared in the mount-path option resulting in a 404.

mount-path was introduced here: #262

DustJS asset path helper (<script src="{@assetPath src="main.js"/}"></script>) works as expected.

Expected Behaviour

if I run:
NODE_ENV=production node app.js -l -c 1 --mount-path=/mypath

I'm expecting all my assets generated by Shunter to be served from: /mypath/public/resources/

Current Behavior

If you reference an assets inside a CSS file using this helper: <%= asset_path('resource') %> it will ignore the mount path option --mount-path=/mypath

Context (Environment)

This will only happens if you use that flag and reference a resource via Mincer asset_path helper.

Hope it is clear enough!
Thanks!
