[Service] Fix DeviceApiRouter with "new Service"
1)
Fix JavaScript error from DeviceApiRouter in case of global service
app created by "new Service".
There are wrong usage with 'id', which should have set 'internelId',
not 'serviceId'.
2)
If there is an exception on onStart() or onRequest(), there is no
change to call finishStartingService().
Thus, it moves finishStartingService on finally section.
