MarcoFalke 6dbc9aba0d Merge #17675: tests: Enable tests which are incorrectly skipped when running test_runner.py --usecli
5ac804a9eb0cdbdcff8b50ecfb736f8793cab805 tests: Use a default of supports_cli=True (instead of supports_cli=False) (practicalswift)
993e38a4e2fa66093314b988dfbe459f46aa5864 tests: Mark functional tests not supporting bitcoin-cli (--usecli) as such (practicalswift)

Pull request description:

  Annotate functional tests supporting `bitcoin-cli` (`--usecli`) as such.

  Prior to this commit 74 tests were unnecessarily skipped when running `test_runner.py --usecli`.

  Before [bitcoin original commit stats]:

  ```
  $ test/functional/test_runner.py --usecli > /dev/null 2>&1
  $ echo $?
  0
  $ test/functional/test_runner.py --usecli 2>&1 | cut -f2 -d'|' | \
      grep -E ' (Passed|Skipped) *$' | sort | uniq -c
        9  ✓ Passed
      126  ○ Skipped
  ```

  After [dash numbers]:

  ```
  $ test/functional/test_runner.py --usecli > /dev/null 2>&1
  $ echo $?
  0
  $ test/functional/test_runner.py --usecli 2>&1 | cut -f2 -d'|' | \
      grep -E ' (Passed|Skipped) *$' | sort | uniq -c
       110  ✓ Passed
       51  ○ Skipped
  ```

  Context: `--usecli` was introduced in f6ade9ce1a

"""Test tx status in case of reorgs while wallet being shutdown.
Wallet txn status rely on block connection/disconnection for its
accuracy. In case of reorgs happening while wallet being shutdown
block updates are not going to be received. At wallet loading, we
check against chain if confirmed txn are still in chain and change
their status if block in which they have been included has been
disconnected.
