Try to dump the autoloader:

Have you installed the dependencies ?
How have you installed slim ?

At a glance it looks like the namespace declaration in AppAction.php ought to be App\Action rather than App\Action\AppAction. In the latter case you would reference the AppAction class as App\Action\AppAction\AppAction::class.
