[ios] Configure audio session once with AVAudioSessionModeVoicePrompt

Browse source 
The audio session is once configured during initialisation and then each time a
audio session is set active. This commit configures the audio session only once
when the app is started. In addition, it sets AVAudioSessionModeVoicePrompt,
which is recommended for apps that use text-to-speech.
