Fix the notification for outgoing call hanged up by the contact

There was a hole in the event logging where we start a call that the
contact hang up. As we dont have an event for outgoing call,
modemmonitor think this is a missed call.

Adding a dedicated event file help modemmonitor to know what happen.
