Send call indicators to all connected devices and resume A2DP

Resume A2DP after call indicators are sent to all
connected devices. This would make sure AG will send
call/call setup end indicators to all connected devices
at the same time and resume A2DP after that. This will
also make sure that stack and app are in sync with
respect to call/call setup updates.
