Handle rollbacks when reading blocks from the chain

[Alenar]

Content

This PR implement on the transaction importer rollback logic. If a Rollback event is received, the importer will:

• Delete the transaction records with a block number strictly greater than the block number of the roll backward chain point.
• Delete the block range root records with a start greater or equal to the start of the block range compute from the roll backward chain point.
