demux/playlist/itml: remove unnecessary branch

An xml-document containing a tag without a name is ill-formed, so this
case will never happen in practice (as the xml-reader will error out
before).

However, if it for some reason would happen, it will be handled due to
the fact that there will not be any handler matching "".
