title: doctrine:schema:update is not updating table
body: <p>Why <code>bin/console doctrine:schema:update --force</code> is not updating database table?</p>
  
  <p>This is an entity:</p>
  
  <pre><code>/**
   * @ORM\Table(name="country")
   * @ORM\Entity(repositoryClass="CoreBundle\Repository\CountryRepository")
   */
  class Country
  {
      /**
       * @var int
       *
       * @ORM\Column(name="id", type="integer")
       * @ORM\Id
       * @ORM\GeneratedValue(strategy="AUTO")
       */
      private $id;
  
      /**
       * @var string
       *
       * @ORM\Column(name="name", type="string", unique=true)
       */
      private $name;
  
      /**
       * @var boolean
       *
       * @ORM\Column(name="active", type="boolean")
       */
      private $active;
  
      ....
      }
  </code></pre>
  
  <p>The table <code>country</code> was created, but there is only <code>id</code> column. 
  I keep getting <code>Nothing to update - your database is already in sync with the current entity metadata.</code> but <code>name</code> and <code>active</code> columns are not added </p>
  
  <p>I am adding Doctrine Configuration too</p>
  
  <pre><code>doctrine:
      dbal:
          driver:   pdo_mysql
          host:     "%database_host%"
          port:     "%database_port%"
          dbname:   "%database_name%"
          user:     "%database_user%"
          password: "%database_password%"
          charset:  UTF8
  
      orm:
          auto_generate_proxy_classes: "%kernel.debug%"
          naming_strategy: doctrine.orm.naming_strategy.underscore
          auto_mapping: true
  </code></pre>
  
  <p><strong>UPDATE</strong></p>
  
  <p>Problem was in Redis. If I remove doctrine caching configurations from config.yml, everything works fine</p>
