Prestashop: CartControllerCore tpl_var 'cart' is overrided by parent 'cart'

[Bonobomagno]

Describe the bug
As you can see, parent is called on the end.

```
//CartController.php
/**
* @see FrontController::initContent()
*/
public function initContent()
{
//..
$presenter = new CartPresenter();
$presented_cart = $presenter->present($this->context->cart, $shouldSeparateGifts = true);

    $this->context->smarty->assign([
        'cart' => $presented_cart,
        'static_token' => Tools::getToken(false),
    ]);

//..
parent::initContent();
}

On the end  FrontendController::initContent is called, and it call 
assignGeneralPurposeVariables, overriding 'cart'.

  ```
// FrontController.php
  protected function assignGeneralPurposeVariables()
    {
        $templateVars = array(
            'cart' => $this->cart_presenter->present($this->context->cart),
            'currency' => $this->getTemplateVarCurrency(),
            'customer' => $this->getTemplateVarCustomer(),
            'language' => $this->objectPresenter->present($this->context->language),
            'page' => $this->getTemplateVarPage(),
            'shop' => $this->getTemplateVarShop(),
            'urls' => $this->getTemplateVarUrls(),
            'configuration' => $this->getTemplateVarConfiguration(),
            'field_required' => $this->context->customer->validateFieldsRequiredDatabase(),
            'breadcrumb' => $this->getBreadcrumb(),
            'link' => $this->context->link,
            'time' => time(),
            'static_token' => Tools::getToken(false),
            'token' => Tools::getToken(),
        );

//..
        $this->context->smarty->assign($templateVars);
//..
    }

that mean that this smarty->assign from CartController do nothing.

Possible chained bug?
none known

How to fix?
just move that parent::initContent() on the top o the CartControllerCore::initContent() function
