changed getErrors() to errors()

I'm simply taking a hint from the validator class. This is way more like the rest of laravel.

From validator:

/**
	 * An alternative more semantic shortcut to the message container.
 *
 * @return Illuminate\Support\MessageBag
 */
public function errors()
{
	return $this->messages;
}

If no rules are passed when saving it should fallback to the static rules property before it tries to pluck the input fields when autoHydrateEntityFromInput is turned on.
