Issue with non relative urls and production building

[antonkomarev]

After using urlAdjuster gulp --production breaking CSS while just gulp is working correctly.

mix.urlAdjuster('public/assets/css/all.css', {
    replace: ['../icons', '/assets/icons']
}, 'public/assets/css');

I'm getting this URLs for google fonts which paths are weren't relative:

http://test.int/assets/icons/http:/fonts.gstatic.com/s/opensans/v13/k3k702ZOKiLJc3WVjuplzC3USBnSvpkopQaUR-2r7iU.ttf

Fonts are importing in CSS this way:

@import url(http://fonts.googleapis.com/css?family=Open+Sans:300italic,400italic,600italic,700italic,800italic,400,600,700,300,800&subset=latin,cyrillic-ext,latin-ext);
