Error: SilverStripe\Versioned\Versioned.versioned was not found

[wernerkrauss]

When adding the Versioned extension in code like

    private static $extensions = [
        Versioned::class . '.versioned'
    ];

I get the following error:

Class SilverStripe\Versioned\Versioned.versioned was not found while trying to analyse it - discovering symbols is probably not configured properly.

This can be fixed by defining an alias in bootstrap.php like:

class_alias(Versioned::class, Versioned::class . '.versioned');

Maybe those injector alias classes can be handled more elegantly.
