Bug report

Noticed that Substreams Block Ingestor backoff instance is never reset in the loop. So the sleep time drops to 30 seconds eventually on an instance with connectivity issues, and never recovers.

Reproduce:

1. Start indexing a substreams subgraph locally
2. Shutdown Postgres docker container and wait until time between retries drops to 30 seconds
3. Start Postgres container back up
4. Shut it down again. It will continue to sleep for 30 seconds between retries even though it would make sense to recover back to 250ms wait times

Should be an easy fix - just reset it every time new cursor is different from latest_cursor
