Merge bitcoin#22992: Fix Qt test broken by bitcoin#22219

865ee1a Fix Qt test broken by bitcoin#22219 (Russell Yanofsky)

Pull request description:

  It looks like this should have been caught by CI but there might have been a conflict with a recently merged PR like bitcoin#19101. Failure was reported by fanquake bitcoin#22219 (comment)

  Fix avoids null WalletClient pointer dereference in address book test by adding MakeWalletClient call and making address book test initialization more consistent with wallet test initialization:
