Bug 159974 – Fix null handling of HTMLMediaElement.mediaGroup

• Component: Media
• Status: RESOLVED FIXED

[Chris Dumez]

Fix null handling of HTMLMediaElement.mediaGroup to match the specification:
- https://www.w3.org/TR/html5/embedded-content-0.html#media-elements

null is supposed to be treated as the String "null".
