Circular references cause infinite loop in 3.0

Steps to reproduce:

1. Get the 3.0 RC build, npm install style-dictionary@next
2. Run this code:

const StyleDictionary = require('style-dictionary');

StyleDictionary.extend({
  properties: {
    color: {
      foo: { value: "{color.foo.value}" },
      teal: { value: "{color.blue.value}" },
      blue: { value: "{color.green.value}" },
      green: { value: "{color.teal.value}" },
      purple: { value: "{color.teal.value}" }
    }
  },
  platforms: {
    css: {}
  }
}).buildAllPlatforms();

And then hear your computer fan spin like crazy.

Closing this as it is now fixed.
