bug: duplicate events received when using multiple namespaces #1644

What happened?

When using FireFly with multiple namespaces, it seems that events of type "blockchain invoke succeeded" and "contract deploy succeeded" are always received multiple times. If I have 7 namespaces, the namespace that triggered the invoke/deploy receives the success event 7 times. Other namespaces don't receive the event at all (which is expected, as it should only be sent to the namespace that triggered it).

What did you expect to happen?

I would expect only one copy of the "blockchain invoke succeeded" or "contract deploy succeeded" event to be delivered back to the namespace that triggered the request.

How can we reproduce it (as minimally and precisely as possible)?

Create multiple namespaces and either deploy a contract or invoke a contract.

Anything else we need to know?
