Steps to reproduce:
Upload audio.ogg
Upload video.ogg as new version
Result:
There is a transcode called "Ogg Vorbis"
Expected behaviour:
Also the audio transcode is purged and therefore wiped.
Note:
This should also apply vice versa but I did not test it. (Upload video first and then audio)
Version: unspecified
Severity: minor
