title: Symfony FOS routes not updating properly for change-password
body: <p>I have a symfony project using <strong>FOS User Bundle</strong> for handling using. </p>
  
  <p>I want to modify the default routes stored in <code>app/config/routing.yml</code></p>
  
  <p>Now changing all of the routes seems to work fine, apart from the <em>change_password.xml</em></p>
  
  <pre><code>fos_user_security:
      resource: "@FOSUserBundle/Resources/config/routing/security.xml"
  
  fos_user_profile:
      resource: "@FOSUserBundle/Resources/config/routing/profile.xml"
      prefix: /profile
  
  fos_user_register:
      resource: "@FOSUserBundle/Resources/config/routing/registration.xml"
      prefix: /register
  
  fos_user_resetting:
      resource: "@FOSUserBundle/Resources/config/routing/resetting.xml"
      prefix: /resetting
  
  fos_user_change_password:
      resource: "@FOSUserBundle/Resources/config/routing/change_password.xml"
      prefix: /psswd
  # this prefix value throws GET error. 
  # without the previx '/change-password` works fine
  </code></pre>
  
  <p>Changing anything in the <em>prefix</em> gives me the Get not found error for route</p>
  
  <blockquote>
    <p>No route found for "GET /psswd"</p>
  </blockquote>
  
  <p>I have cleared the cache and everything seems to work fine. </p>
  
  <p>Can anyone tell me why such problem would occur?</p>
  
  <h2>Update</h2>
  
  <p>It turns out path <code>/psswd</code> doesn't work <strong>but</strong> path '/psswd/change-password` works fine :I </p>
