FIX charset=None was causing SubscriberProtocol.messageReceived to ne…

…ver be called

If the charset = None in SubscriberProtocol then SubscriberProtocol .replyReceived will never call SubscriberProtocol.messageReceived due to u"message" when received will not match b"message" and u"pmessage" will not match b"pmessage" inside the if clauses therefore the code where messageReceived is called will never be reached. This is due to types of str and bytes will not match each other even if similar values are inside
