[bowenwang1996]

@Longarithm fixed #11135 by forcing flat storage head to move after state sync. The pytest single_shard_tracking exposes this issue.

Instructions to run the test

cargo build -p neard --features test_features,statelessnet_protocol
python3 pytest/tests/sanity/single_shard_tracking.py

Fixed test test_dump_epoch_missing_chunk_in_last_block because in test envs flat storage is not always present.
Added test to nayduck: https://nayduck.nearone.org/#/run/67
Let's also remove extensive debug output.
