dag: fix benches/inprocess_iddag_serde

Browse Source 
Summary:
Benchmark code is out of sync. Fix it.

Example run:

  benchmarking dag::iddag::IdDag<dag::iddagstore::in_process_store::InProcessStore> serde
  serializing inprocess iddag with mincode            0.664 ms
  mincode serialized blob has 707565 bytes
  deserializing inprocess iddag with mincode         42.477 ms
