Remove duplicated calls to `loadApps` by consolidating the logic.
- First we keep loading authentication apps
- Then we try to login the user if needed
- Then load filesystem and logging
- Then - if not CLI - load everything else (if possible)
The flow is not really changed, but tried to make it more clear at what
step which apps are loaded.
This also allows to have a specifc point in the execution flow where all
app loading is done so we can emit an event for this in the future.
