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:
a31be09bfd and
7e89994133 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.

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)).
