Fix device call logging issues in skinny

Skinny device call logging (ie missed, place and received calls) has issues 
because the incorrect sequence of callstates is/can be sent to the device.
This patch removes some extra callstate updates driven by forces external
to skinny and ensures the needed intermediary callstate messages are sent.
