InvalidAccessError when calling clearTimelineState or destroy in Microsoft Edge

[kruncher]

The "InvalidAccessError" error occurs in some circumstances when the clearTimelineState or destroy methods are called of the MediaNode.

The problem seems to be caused by the following line: https://github.com/bbc/VideoContext/blob/develop/src/SourceNodes/medianode.js#L198

It seems that Microsoft Edge does not allow one to assign undefined to srcObject; but it does appear to like having null assigned to it.

Thanks for reporting this. Which version of Edge are you using?
