wallet: Minimal fix to restore conflicted transaction notifications
This fix is a based on the fix by Antoine Riard <ariard@student.42.fr> in https://github.com/bitcoin/bitcoin/pull/18600. Unlike that PR, which implements some new behavior, this just restores previous wallet notification and status behavior for transactions removed from the mempool because they conflict with transactions in a block. The behavior was accidentally changed in two `CWallet::BlockConnected` updates: a31be09bfd77eed497a8e251d31358e16e2f2eb1 and 7e89994133725125dddbfa8d45484e3b9ed51c6e from https://github.com/bitcoin/bitcoin/pull/16624, causing issue https://github.com/bitcoin/bitcoin/issues/18325. The change here could be improved and replaced with a more comprehensive cleanup, so it includes a detailed comment explaining future considerations. Fixes #18325 Co-authored-by: Antoine Riard <ariard@student.42.fr>

+Notification changes
+--------------------
+
+`-walletnotify` notifications are now sent for wallet transactions that are
+removed from the mempool because they conflict with a new block. These
+notifications were sent previously before the v0.19 release, but had been
+broken since that release (bug
+[#18325](https://github.com/bitcoin/bitcoin/issues/18325)).
