Fix duplicate registration assetBundle

[onmotion]

If disable asset bundle (for example for ajax requests), if js created through init() this js assets will be forced registered anyway (although it should not)

if (\Yii::$app->request->isAjax) {
            $renderMethod = 'renderPartial';
            \Yii::$app->assetManager->bundles = false;
}
