chain: avoid using defer for BitcoindClient onRescanFinished notification

Since defer will copy the function with the parameters evaluated at its
invocation, the RescanFinished notification would be dispatched with the
incorrect block. To fix this, we'll just send the notification at the
end ourselves manually.
