This would be better if the delegate listened to the signin delegate itself as
it would then have 100% responsibility for knowing when changes to the profile
occur.

If you do that then AppListView can just listen to the model and update itself
when the profile changes and this function just becomes
OnAppListodelProfilesChanged() below.

Done.
