This looks good to me, what are the situations where a double notification can happen (without a failure)? Are actor notifications broadcast multiple times?

The scenario where I've seen it happen so far is when a node manager receives an actor task that it doesn't have a location for yet, so it does a lookup. Then it receives the published notification along with the lookup response, so it gets a duplicate notification. I think it's necessary to keep the lookup step, though, in case there's a node that joins the cluster after some actor notifications have already been published. |

What do these changes do?
An actor creation notification may be processed twice by a raylet if the initial publication is slow. The check for duplicate actor notifications is too strict, causing the raylet to crash if a duplicate notification is received. This PR relaxes the check to just make sure that if a duplicate notification is received, the node manager IDs match.
