[NO ISSUE][ING] Prevent duplicate active runtimes in NCs

- user model changes: no
- storage format changes: no
- interface changes: no

details:
- Previously, when an active runtime is registered, we ignore
  if the runtime id is already registered.
- After this change, such operation will throw an exception.
