Cron image not running when the instance has not been initalized

Durig updating the images for 2025.07 (rc) I realized the following behaviour:

Setting up a friendice instance with docker-compose including a mariadb, one friendica container for the app and a second one for cron jobs (starting with cron.sh) plus a nginx.

The cron container keeps exiting with the message:
```
cron_1 | [Error] Friendica isn't properly installed yet
test2_cron_1 exited with code 0
```

After setting up basic configuration the cron container messaged
`cron_1 | Starting Friendica daemon`
and kept running.

I see this behaviour annoying (at least for new users) and suggest that the cron container shall keep running after start.

@nupplaphil, what is your opinion to this?
