Sass build fails if light color is not present.

Short description of the problem:

The Sass portion of the Ionic 2 RC0 build process will fail with the following message if a color named light is not present in the color map in variables.scss:

[17:39:58]  Sass Error: line: 80, column: 3


  The value `` must be a color.
  If you are setting the value as a map make sure
  both the base and contrast are defined as colors.

  For example:

  $colors: (
    primary:    #327eff,
    secondary:  (base: #32db64, contrast: #000),
  );
[17:39:58]  sass failed:  Sass compile error
Error running ionic app script "build": Error: Sass compile error

What behavior are you expecting?

As the comment in variables.scss claims that the only required color name is primary, I would expect compilation to succeed if none of the other color names are defined.

Steps to reproduce:

1. Create a new Ionic project (I used ionic start test --v2).
2. Remove the light color from variables.scss at line 29.
3. Attempt to build with npm run build.

insert any relevant code between the above and below backticks

Which @ionic/app-scripts version are you using?

ionic-app-scripts 0.0.30

Thanks for the issue! This is a duplicate of ionic-team/ionic-framework#8266 and it will be fixed in Ionic itself. :)
