This is a followup of the fix root-project#20352 for issue root-project#20320: When snapshot with variations is run with JIT-ted filters, the computation graph first needs to be JIT-ted before reading Defines or Filters. In the fix for that case, an iterator invalidation on push_back caused crashes, because vector.reserve() had been called with the wrong size. Here, the size is corrected, but more importantly, instead of saving the iterator, the shared_ptr it points to is saved. This makes the code independent of the underlying storage.

This is a followup of the fix #20352 for issue #20320:
When snapshot with variations is run with JIT-ted filters, the
computation graph first needs to be JIT-ted before reading Defines
or Filters. In the fix for that case, an iterator invalidation on
push_back caused crashes, because vector.reserve() had been called
with the wrong size.
Here, the size is corrected, but more importantly, instead of saving the
iterator, the shared_ptr it points to is saved. This makes the code
independent of the underlying storage.
