Plugin didn't respect to the setting of configureAudioSession on iOS

[ming-chu]

The plugin at version 2.0.4+2 didn't respect to the configureAudioSession setting.

After called setCallConnected method it will reset the configureAudioSession to true from Data since it only pass the args {'id': id} for the initialization of Data.

// e.g:
FlutterCallkitIncoming.setCallConnected('xxx-xxx-xxx');

flutter_callkit_incoming.dart#L94-L99

SwiftFlutterCallkitIncomingPlugin.swift#L166-L178

the self.data.configureAudioSession will be true at line:176 now even we pass the configureAudioSession to false when calling FlutterCallkitIncoming.startCall(params) before.

https://github.com/hiennguyen92/flutter_callkit_incoming/blob/2.0.4%2B2/ios/Classes/Call.swift#L218

and then connectedCall method will request the CXAnswerCallAction transaction from the CXCallController which will lead CXProviderDelegate being called in SwiftFlutterCallkitIncomingPlugin.swift.

and the delegate method call the configurAudioSession() again with data?.configureAudioSession => true:
