adaptivedemux: add replaced flag to not error out on bitrate change

When switching bitrates we set the old streams as cancelled, but it
could also be confused with a cancel due to other reasons (as an error)
and it would lead the element to stop the pipeline mistankely. This
would happen when the stream being replaced was waiting for a manifest
update on live. Ss make it sure that we are stopping for switching
bitrates to avoid erroring out.
