1. Optimize handling of non-existing transactions in the Electrum client …

   Electrum client exposes two methods for getting entire transactions
   and transaction confirmations from the Bitcoin blockchain. Those
   methods retry Electrum requests in case of any error. Retries are
   done in the exponential backoff scheme until a timeout of 2 minutes is hit.
   
   However, when the given transaction does not exist on the chain, there
   is no point to retry. This can be harmful for scenarios like deposit
   sweep generation that need to check multiple transactions in a limited
   time window. If there are multiple non-existing transactions that are
   checked during the process, 2 minutes per such transaction is wasted.
   
   Here we improve the situation by introducing an error type check.
   If the error says about not found transaction, retries are not executed.
