Enabling debugging with autoinstall via env variables seems brocken

I created a new instance with docker-compose (using autoinstall) where the env variables

```
- FRIENDICA_LOGFILE=/tmp/friendica.log
- FRIENDICA_LOGLEVEL=debug
- FRIENDICA_DEBUGGING=true
```

are set.

Executing into the friendica container before trying to register the admin user showed that no log has been created. The env variables passed are available.

After registering the admin user with `bin/console user add` and logging into the instance the `Logs` settings under `Admin` showed:


It seems obvious that the log is not created and logging not enabled as expected.

Reproduce the docker-compose autoinstall setup with FRIENDICA_LOGFILE, FRIENDICA_LOGLEVEL, and FRIENDICA_DEBUGGING set, then inspect the container environment and run bin/console user add. Compare the configured values with the Admin Logs settings and verify that the expected log file is created and debug logging is enabled.
