Skip reconciliation when interesting account is missing

[septerr]

Motivation

1. There is a bug in our reconciliation logic around missing accounts. When an interesting account is configured, the reconciler may stop with an error like below:

Error: unable to get computed balance for &{Address:0000000001 SubAccount:<nil>, Metadata:map[]}: &{Symbol: ICP Decimals:8 Metadata:map[]}: block nil

The reconciler reconciles interesting accounts at every block height. But, there is no entry for an account in balance storage until it is encountered in a block. So, when the reconciler tries to reconcile an interesting account, it hasn't encountered yet, it stops with an account missing error (ErrAccountMissing).

2. The error message for ErrAccountMissing incorrectly says "block nil".

Solution

1. Updated the reconciliation logic to skip reconciliation for missing accounts.
2. Fixed error message.
