jormungandr: not yet implemented: method to load a Ref from the storage is not yet there

Describe the bug When restarting a node with trusted peer this happen:

To Reproduce Steps to reproduce the behavior: 1. nix-shell https://github.com/input-output-hk/jormungandr-nix/archive/listen-address.tar.gz --argstr trusted_peers /ip4/3.122.73.200/tcp/3000 2. mkdir storage 3. uncompress/copy attached sqlite db into the storage folder 4. RUST_BACKTRACE=1 run-jormungandr

Expected behavior the node start correctly.

Additional context the genesis block of the cluster was generated using the following command: nix-shell https://github.com/input-output-hk/jormungandr-nix/archive/listen-address.tar.gz --arg numberOfStakePools 7 --arg faucetAmounts '[ 1000000000 1000000000 1000000000 1000000000 1000000000 1000000000 1000000000 100000000 100000000 100000000 ]' --arg slots_per_epoch 21600 --arg slot_duration 20 --arg consensus_genesis_praos_active_slot_coeff 0.1 --arg kes_update_speed 86400 --arg numberOfLeaders 7
