android(fix): set HSP/HFP policy to allow when connecting to audio (#318)

* android: use setConnectionProfile instead of (dis)connect on BluetoothProfile

this prevents android from trying to reconnect to audio itself after we disconnect. this is essentially the same as toggling the 'Media Audio' and 'Phone Calls' settings in the android settings

* android(fix): set HSP/HFP policy to allow when connecting to audio

forgot to change it
