Title: Fix for checking rules

`$item->ruleName === null` don't works with `DbManager`.

Generates `yii\base\InvalidConfigException` with message `Rule not found:`, although item is empty

```
yii\rbac\Role#1
(
[type] => '0'
[name] => 'projects.index'
[description] => 'Проекты: список'
[ruleName] => null
[data] => null
[createdAt] => '0'
[updatedAt] => '0'
)
```
