Investigate missing chunks

[khorolets]

While syncing testnet from genesis, we've encountered a lot retries for storing receipts, they are infinite because they can't find the parent. Investigation of the reason showed that the parent transactions for these receipts were not stored and then we've found out that the chunk which contains particular parent transactions hasn't been added to database.

For example this one chunk hash H6MvjzT6JtqzuJiPNGennqBDhtqXfDcb2e8cL5NLNcgU (block height 22303582)

We need to investigate why Indexer hasn't store this chunks and similar ones and fix it.
