Exception on server side leaves dangling client

[neworld]

Describe the bug
Consider server code:

routing {
    rpc("rpc") {
        error("Random error for what ever reason")
        registerService<Main> { MainService() 
    }

When service access dangles forever.

val rpcClient = client.rpc { ... }
val mainService = rpcClient.withService<Main>()
mainService.checkStatus() // <-- It is a suspend function

Expected behavior

Cancellation exception from checkStatus()

Additional context
Version: 0.10.0

The WS connection was closed immediately without any message to the client

My guess is that #505 fixed this, we'll see in 0.10.1, I'll ping you on release
