Revert "dashdemux: Fix issue when manifest update sets slow start without passing necessary header & caps changes downstream"

Browse source 
This reverts commit c9fbf3459a.

The representation ID comparision here was wrong and triggering always
if the ID did *not* change, causing needless redownloading of the
header. The sample stream provided in the bug does not exist anymore.
