Subject: [PATCH 23/26] Blockchain watcher safety adjustments (#411)

* Fix a failed block potentially being skipped. Up retry sleep to 2 minutes, up number of failed requests to 10 to give blockchain more time to recover.

* Fix non-transaction vouts causing issues.

* Wrap whole scan function in try. Reduce retry time to 1 minute.
