dynamically registered services do not update after broker reconnect

[fugufish]

When a separate broker reconnects, dynamically registered services (any service that calls .createService after moleculer starts) are not updated because the sequence is out of sync.

I traced the issue here:

fbb9910#diff-bb81619136bf2c8b0778ee961b076a8cR184

Basically, the sequence # sent in the payload is less than the sequence # stored in the remote broker, ensuring that newly created services are not added to the registry.
