* [IdealoBridge] Fix price comparison and some PHP Notice - The prices were compared as String and the comparison was wrong in some case : now the price are converted to float before the comparison, so the logic works really. - Don't show a new or used product price if it does not exist : this prevents a PHP Notice to be thrown * [IdealoBridge] Fix price conversion in case the price is null The conversion as float of the text price won't work if the price is null : we retunr null in this case now.
