docker logs are useless, while relevant logs are in nextcloud.log

[spaceone]

univention-app logs nextcloud calls docker logs for the running nextcloud container.
These information are useless, instead in the container /var/lib/univention-appcenter/apps/nextcloud/data/nextcloud-data/nextcloud.log exists, which contains the relevant data.
Maybe it can be changed, so that the docker logs contain the same output?
