Error when files array is empty

[tykarol]

When files array is empty then throw error in console:

Module build failed: Error: "options.files" is empty.
at webfont (...\node_modules\webfonts-generator\src\index.js:49:41)
at Object.module.exports (...\node_modules\fontgen-loader\index.js:155:5)

Probably fontgen-loader should check files array and if is empty do not run webfonts-generator.
