The Update Metadata workflow should not be started when preceding workflows failed

[tibroc]

Currently the cronjobs seem to trigger update metadata workflows even if the initial workflow of the event failed (see #910). This has a confusing effect in opencast because the event will be shown in the admin UI as "finished" instead of "failed" because the update metadata workflow finished correctly (although the overall event status should still be failed).

I think you mean the republish-metadata workflow. The workflow is triggered after editing the video in the UI and in the checkEventACL function triggered by the "Opencast - Queue" cronjob:

studip-opencast-plugin/lib/Models/Videos.php

Line 762 in e589d29

$workflow_client->republish($video->episode);

After #916 this workflow should not be triggered by the cronjob anymore when uploading videos. Still, this workflow is executed for recordings in OC Studio, as Studio runs independently of this plugin and does not set the required ACLs. One problem is that the plugin does not know the event ID of the recorded video a priori.
