`connect()` followed by immediate `attach()` results in initialized state instead of attaching

[ttypic]

Way to reproduce:

realtimeClient = AblyRealtime(ClientOptions().apply {
   //...
   autoConnect = false
}) 
realtimeClient.connect()
realtimeClient.channels.get("channel").attach()

Expected:

realtimeClient.channels.get("channel"): initialized -> attaching -> attached states

Actual:

realtimeClient.channels.get("channel"): initialized -> attaching -> initialized states
