Reopens the MediaSource when SourceBuffer::Remove is called on an Ended
MediaSource. Only run the Range Removal algorithm when MediaSource
duration is changed instead of calling Remove on SourceBuffers.
Updates tests for the fact that update{start,end} can now be called
more than once due to DurationChange.
