[iOS AzureCommunicationCalling 1.0.1] Call state return .none when the network is intermittent and call end has no callback for the first tap

[AmyL219]

Describe the bug The call state would return .none after the internet connection is interrupted for 1 minutes.

To Reproduce Steps to reproduce the behavior:

1. Join a call successfully with good network condition
2. call state return .connected
3. Open airplane mode for more than 1 minutes
4. call state return .none
5. end the call by call.hangUp
6. There is no callback for the first call hangUp. If you call hangUp again, it would have a callback

Expected behavior When the network is interrupted, the callState should return .disconnected rather than none. And the endCallReason should indicate it's because of network issue
