ActorPath.Equals fix and SetReceiveTimeout

This was supposed to be a PR just for `SetReceiveTimeout` but I included the small fix for `ActorRef:Equals` also for #240 
The definition for RootActorPath is 
```final case class RootActorPath(address: Address, name: String = "/")```
It's a case class and JVM Akka is calling equals on RootActorPath (hence the left / right juggling).
The case class is generating an equals that compares both Address and Name for RootActorPath
The JVM version doesn't do the address comparison until it gets to the RootActorPath. Assuming there is a reason for that it might be better to switch the Address.Equals and the SequenceEquals
