Cardano transaction importer does not import the last block advertised as certified

[jpraynaud]

Why

The Cardano transaction importer does not import the last block displayed as certified:

• In the aggregator artifact route:

  {
  "merkle_root": "05e65f0c58565d1097254ae35432a61a26f06426b2a723ecdac63126bd5d595e",

  }

• In the aggregator logs:

What

Import the missing block with the Cardano transaction importer:

• block number in the pending certificate should be: 10499369 (last block number signed by a block range, add an explanation in the code)
• block number in the artifact should be: 10499369
• block number in the Cardano transactions store should be at least: 10499369

How

• [x] Investigate why the latest block is not imported
• [x] Fix the problem that prevents the last block to be imported
