title: Yii2 Error: yii\base\UnknownMethodException: Calling unknown method: yii\web\UrlManager::addRules()
body: <p>After todays update of composer dependencies (with composer update command) my Yii2 application became broken - It throws <strong>Unknown Method – yii\base\UnknownMethodException: Calling unknown method: yii\web\UrlManager::addRules()</strong></p>
  
  <p>After inspecting <em>vendor/yiisoft/yii2/web/UrlManager.php</em> file I found that there is no method addRule.
  And the whole entire class <em>UrlManager</em> is different from the class in the repository.</p>
  
  <p>My composer.json:</p>
  
  <pre><code>"minimum-stability": "dev",
  "require": {
      "php": "&gt;=5.4.0",
