Race condition when starting the module

[fjordansilva]

If in the mongo database there are any pending messages when the module is starting, in the start() method there is a check to load and send those messages:

if (persistorAddress != null) {
loadMessages();
}

But at this moment, there isn't any registered processor that can handle the delivery of the loaded messages. So those messages are never processed.

I think that the best place to check if there is any pending message is in the handler when registering a processor for a first time or maybe add a new address to be called when the module is deployed and the processors are configured (maybe "<module_address>.pending" )
