Fix bug for temp-service-delete

Fix bug for temp-service-delete

- Currently, temp-service-delete does not work and creates a
  null-pointer exception, when used. The code uses service-list
  instead of temp-service-list to retrieve data for the delete
  operations.
- Add additional code to retrieve the data from the temp-service-list
- Update transport-pce-service-list after the temp-service is deleted
- Update temp-service-list after the temp-service-delete
