Transaction index not properly working

[hclivess]

There is a problem in block 502141, all transactions are in the block but they are not indexed - and not reflected, which is critical.

Block in question: http://167.86.120.22:9173/get_block?hash=c9a319e69506d30e29dcd56cb755147c4a9d98d66fd5eb60b8068e902f88e928
Transactions are present in the raw block data

Links to txs exist but return 404, which means they are not present in the transaciton index. Also they are not reflected in accounts (!)

Risk: Critical - reindexing can lead to respending of the transaction absent from tx index and not reflected in balances but present in the block (top authority), forking

Suspects:

• Rollback mechanism, perhaps in combination with the recently introduced index partitioning
• executemany - there have been issues in the past with Bismuth

Added infinite retries on db operations so locks don't skip them
