Merge #10330: [wallet] fix zapwallettxes interaction with persistent mempool
4c3b538 [logs] fix zapwallettxes startup logs (John Newbery)
e7a2181 [wallet] fix zapwallettxes interaction with persistent mempool (John Newbery)
ff7365e [tests] fix flake8 warnings in zapwallettxes.py (John Newbery)

Pull request description:

  zapwallettxes previously did not interact well with persistent mempool.
  zapwallettxes would cause wallet transactions to be zapped, but they
  would then be reloaded from the mempool on startup. This commit softsets
  persistmempool to false if zapwallettxes is enabled so transactions are
  actually zapped.

  This PR also fixes the zapwallettxes.py functional test, which did not properly test this feature. The test line:

  ```py
       assert_raises(JSONRPCException, self.nodes[0].gettransaction, [txid3])
       #there must be a expection because the unconfirmed wallettx0 must be gone by now
  ```
  is not actually testing the presence of the transaction since the RPC is being called incorrectly (with an array instead of a string). The `assert_raises()` passes since an assert is raised, but it's not the one the test writer had in mind!

  Fixes #9710 .

"""Test the zapwallettxes functionality.
- start two bitcoind nodes
- create two transactions on node 0 - one is confirmed and one is unconfirmed.
- restart node 0 and verify that both the confirmed and the unconfirmed
transactions are still available.
- restart node 0 with zapwallettxes and persistmempool, and verify that both
the confirmed and the unconfirmed transactions are still available.
- restart node 0 with just zapwallettxed and verify that the confirmed
transactions are still available, but that the unconfirmed transaction has
been zapped.
