registration: Initialize PSR-4 namespaces at same stage as normal autoloader

readFromQueue() injects the content of AutoloadClasses to
$wgAutoloadClasses however it missed doing the same for
AutoloadNamespaces.

When using the installer with an extension having AutoloadNamespaces
set, its classes would not be found.

Make ExtensionRegistry append to AutoLoader::$psr4Namespaces, and add
a test to cover the new behavior.
