Tomas Gunnarsson de6e1b4ffd Use demuxer_criteria_.mid() for content_name() in BaseChannel.
BaseChannel::content_name() is consistently used as the mid throughout
the code and the mid is stored in the demuxer criteria. Furthermore
there's a chance that the two variables might not be in sync if the
mid needs to be truncated, so it's better to use one source of truth.
