Fixed logException twice in CartController.php

[kiatng]

Description (*)

See line 226

magento-lts/app/code/core/Mage/Core/Model/Session/Abstract.php

Lines 224 to 229 in 1243a21

	public function addException(Exception $exception, $alternativeText)
	{
	Mage::logException($exception);
	$this->addError($alternativeText);
	return $this;
	}

The exception is logged, no need to do it twice.

I searched and checked the entire repo, it seems this only happens in CartController.php.
