Merge #13079: Fix rescanblockchain rpc to properly report progress
16be13345 Fix rescanblockchain rpc to property report progress (Ben Woosley) Pull request description: Previously it assumed tip in all cases. This also extracts a RescanVerificationProgress helper object whose role is to manage reporting, in order to simplify ScanForWalletTransactions - more lines in total, but much simpler to follow the core logic.
