Updating reconnect retry code for InCallUI.

After we failed to retry our maximum number of times, we never retried
again until the device was restarted.  This is because the only place
we reset the retry count was on successfull connection.

1) Dont stop trying to connect as long as there is a live call. Instead,
move to a much slower 30-second retry interval.
2) Reset the retry count when a new incoming call comes in.
