Russell Yanofsky c1585bca8d test: Get rid of default wallet hacks
- Get rid of hardcoded wallet "" names and -wallet="" args
- Get rid of setup_nodes (-wallet, -nowallet, -disablewallet) argument rewriting

Motivation:

- Simplify test framework behavior so it's easier to write new tests without
  having arguments mangled by the framework
- Make tests more readable, replacing unexplained "" string literals with
  default_wallet_name references
- Make it trivial to update default wallet name and wallet data filename for
  sqlite #19077 testing
- Stop relying on -wallet arguments to create wallets, so it is easy to change
  -wallet option in the future to only load existing wallets not create new
  ones (to avoid accidental wallet creation, and encourage use of wallet
  encryption and descriptor features)
