Removing <source> should make resource selection not fire 'error' on it

The resource selection algorithm will, after async finding out that a  
<source> is not usable, fire an 'error' event on the candidate <source>  
element. However, a script might have removed that element from the tree,  
possibly inserted it into another <video> element or just removed all  
references to it, etc, which might have various interesting behaviors.

We suggest that when a <source> element is removed from a document, or  
when it is moved in the document (including being moved inside the same  
parent), the resource selection algorithm should not fire the 'error'  
event to it. This seems like the simplest thing to implement, and there  
doesn't seem to be any use case to moving <source> elements anyway.
