    core: Downgrade init failure to a debug statement
    
    It's quite common for plugin load to fail when it lacks the
    necessary API keys, especially when the plugin type isn't
    supported by the application.
    
    Eg. we don't want Totem to warn if it cannot load the Flickr
    plugin that it will not be using.
