1168394d759b13af68acec6d5bfa04aaa24561f8 [wallet] Notify conflicted transactions in TransactionRemovedFromMempool (John Newbery)

Pull request description:

  These boost signals were added in #9371, before we had a `TransactionRemovedFromMempool` method in the validation interface. The `NotifyEntryAdded` callback was used by validation to build a vector of conflicted transactions when connecting a block, which the wallet was notified of in the `BlockConnected` CValidationInterface callback.

  Now that we have a `TransactionRemovedFromMempool` callback, we can fire that signal directly from the mempool for conflicted transactions.

  Note that #9371 was implemented to ensure `-walletnotify` events were fired for these conflicted transaction. We inadvertently stopped sending these notifications in #16624 (Sep 2019 commit 7e89994). We should probably fix that, but in a different PR.

    Code review ACK e57980b4738c10344baf136de3e050a3cb958ca5, no code changes since previous review, but helpful new code comments have been added and the PR description is now more clear about where the old code came from
