title: Symfony3 Doctrine schema update after switched git branch displays error
body: <p>For a Symfony 3.4 project, after having switched on an existing branch on git, I made a</p>
  <pre><code>php bin/console doctrine:schema:update --force
  </code></pre>
  <p>in order to create new needed fields in database.</p>
  <p>I'm facing an error:</p>
  <blockquote>
  <p>In AbstractMySQLDriver.php line 60:  An exception occurred while
  executing 'SELECT t0.id AS id_1, t0.name AS name_2, t0.real_name AS
  real_name_3, ...</p>
  </blockquote>
  <blockquote>
  <p>SQLSTATE[42S22]: Column not found: 1054 Unknown column 't0.real_name' in 'field list'</p>
  </blockquote>
  <p>That's precisely the field I want to add in my database, so why I am getting this error ?</p>
  <p>Tried doctrine:cache:clear-metadata, cache:clear, ...,</p>
  <p>Thank you for your help.</p>
