[GH-124] Connection quote() ignores returned value from getBindingInfo()

Message:

Maybe I'm missing something here, but this simple change seems to be necessary to allow for proper type management in quote(). For example, without this change passing a DateTime object as $input with $type = 'date' will resolve the proper string value in getBindingInfo, but then still attempt to pass the DateTime to PDO, which of course doesn't work.
