dced203162 wallet, tests: mark unconflicted txs as inactive (ishaanam)
096487c4dc wallet: introduce generic recursive tx state updating function (ishaanam)

Pull request description:

  This implements a fix for #7315. Previously when a block was disconnected any transactions that were conflicting with transactions mined in that block were not updated to be marked as inactive. The fix implemented here is described on the [Bitcoin DevWiki](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking#idea-refresh-conflicted). A test which tested the previous behavior has also been updated.

  Second attempt at #17543
