locAPIRemoveGeofences roolback to async result notification

Browse source 
locAPIRemoveGeofences is rolled back to async result notification,
using the RemoveGeofencesRequest, but using a new temporal bidict
of sessions & ids, to avoid a previous race condition using the
wrong id when removing and adding a geofence.
