Merge #16394: Allow createwallet to take empty passwords to make unencrypted wallets

Browse Source 
c5d3787367 Allow createwallet to take empty passwords to make unencrypted wallets (Andrew Chow)

Pull request description:

  Allow createwallet to take the empty string as a password and interpret that as leaving the wallet unencrypted. Also warn when that happens.

  This fixes a bug where it was not possible to use the `avoid_reuse` option for new unencrypted wallets without using named arguments.Thus this allows more `createwallet` options to be added that can be set on unencrypted wallets when using positional arguments.

    utACK c5d3787367. Changes since last review are rebasing, concatenating warning strings to avoid discarding warnings, adding release notes, and choosing an unambiguous wallet name for the test.

RPC changes
-----------
`createwallet` now returns a warning if an empty string is used as an encryption password, and does not encrypt the wallet, instead of raising an error.
This makes it easier to disable encryption but also specify other options when using the `bitcoin-cli` tool.
