Issue: #6501 Wrong segmentNumShift was calculated in copyWithNewRepresentation

Browse Source 
In DefaultDashChunkSource.copyWithNewRepresentation, it will handle the logic that
new MPD manifest file is updated and calculate a newSegmentNumShift for furthermore
segNum index calculation in getSegmentUrl, when a shorter window MPD updated and then
back to a longer window MPD, copyWithNewRepresentation will go into the overlap case
but the new index actually contains the old index..
