// Because mockShardLeaderActor is created at the top level of the actor system it has an address like so,
// akka://cluster-test@127.0.0.1:2559/user/member-2-shard-default-config1
// However when a shard manager has a local shard which is a follower and a leader that is remote it will
// try to compute an address for the remote shard leader using the ShardPeerAddressResolver. This address will
// look like so,
// akka://cluster-test@127.0.0.1:2559/user/shardmanager-config1/member-2-shard-default-config1
// In this specific case if we did a FindPrimary for shard default from member-1 we would come up
// with the address of an actor which does not exist, therefore any message sent to that actor would go to
// dead letters.
// To work around this problem we create a ForwardingActor with the right address and pass to it the
// mockShardLeaderActor. The ForwardingActor simply forwards all messages to the mockShardLeaderActor and every
// thing works as expected
