Non interactive koel:init (#886)

* Use ADMIN_* variables if available to create the admin account

* Add APP_MEDIA_PATH for media directory

* Use the standard --no-interaction flag to koel:init

* Undo variable aligment and code formatting

* Prefer early return over else, add new line before return statements

* Some fixes
