Add support for creating a chart from the canvas id and prevent exceptions, at construction time, when the given item doesn't provide a valid CanvasRenderingContext2D or when the getContext API is not accessible (e.g. undefined by add-ons to prevent fingerprinting). New jasmine matcher to verify chart validity.
