  1. cluster: guard against undefined message handlers 

    cluster's internal message handling includes a cache of callback
functions. Once the message for that callback is received, it is
removed from the cache. If, for any reason, the same message ID
is processed twice, the callback will be missing from the cache
and cluster will try to call undefined as a function. This commit
guards against this scenario.
