Describe the bug
A clear and concise description of what the bug is.

• In the 'AzureCommunicationCalling version 1.1.0-beta.1 is working, but there was a breaking change in 2.0.0-beta.1 that we need to do some refactoring regarding the RecordingFeatureDelegate and TranscriptionFeatureDelegate
• When joining a Teams meeting through interop, and start recording the meeting, it will start BOTH recording and transcription, but the delegate method with the following code will receive these 3 events in order:
  1. newTranscriptionActive: true
  2. newTranscriptionActive: false
  3. newRecordingActive: true

func recordingFeature(_ recordingFeature: RecordingFeature, didChangeRecordingState args: PropertyChangedEventArgs) {
        let newRecordingActive = recordingFeature.isRecordingActive
        print("newRecordingActive: \(newRecordingActive)")
    }

func transcriptionFeature(_ transcriptionFeature: TranscriptionFeature, didChangeTranscriptionState args: PropertyChangedEventArgs) {
        let newTranscriptionActive = transcriptionFeature.isTranscriptionActive
        print("newTranscriptionActive: \(newTranscriptionActive)")
    }

• But on Teams client it will show both recording and transcription is on
• And when the Teams client Stop transcription, the sdk does not receive event that isTranscriptionActive = false

To Reproduce
Steps to reproduce the behavior:

1. Join teams interop meeting
2. Start recording from teams client (will start both recording+transcription)
3. Print from delegate method will observe the following event
4. newTranscriptionActive: true
5. newTranscriptionActive: false (this should not happen)
6. newRecordingActive: true
7. Stop transcription from teams client, but does not receive isTranscriptionActive=false

Expected behavior
A clear and concise description of what you expected to happen.

• When starting recording from Teams client will start both recording and transcription
• Should receive isTranscriptionActive=true and isRecordingActive=true, the transcription should not receive additional event saying its false when Teams have transcriptionActive
