Make alternate tape name metadata stick
Currently removing 'alternate tape name' metadata appears to write to the source file (dare modified changes) but it resets to previous entry if PP restarts.
Why is this important? We have an archive library that has added 'time' as a tape name to all clips. This then gets assigned to 'alternate tape name' by PP. This then results in false positives for dupe detection. Removing the entry for alternate tape name removes the false positives. Until PP is restarted
