Resubscribe on client disconnection throws an exception #4
Description
Hi,
When using the resubscribe option (which I believe is default behavior), I get an exception throw when a client disconnects and reconnects.
The error is throw on this line: https://github.com/boneskull/mqttletoad/blob/master/lib/index.js#L59
The 'topic' argument passed is not a string but an object instead, and no listener argument is passed.
This is called by MQTT.js upon reconnection (I believe that is a result of monkey-patching the subscribe function):
https://github.com/mqttjs/MQTT.js/blob/master/lib/client.js#L215
The only argument passed is a dictionnary of topics we were previously subscribed to.
Since I'm not calling that function, I can't catch the exception properly to handle it, and the MQTT part of my application stops working altogether.
Disabling resubscriptions is not really an option for me. Perhaps I can help sort out resubscriptions with your library? Does toad keep its own dictionnary of subscribed topics and associated listeners?
