In Windows, Bitcoin Core use (datadir) instead of (datadir)/wallets/ as wallet directory by default. #13104

Describe the issue

In Windows, Bitcoin Core do not use (datadir)/wallets/ as wallets dir by default, but use (datadir).

What behavior did you expect?

I think the default wallet directory in Windows should be as the same as in Linux.

What was the actual behavior?

Bitcoin Core use (datadir) as wallet dir in Windows

How reliably can you reproduce the issue, what are the steps to do so?

Start bitcoin-qt or bitcoind with wallet enabled on Windows.

<!-- What version of Bitcoin Core are you using, where did you get it (website, self-compiled, etc)? -->

<!-- What type of machine are you observing the error on (OS/CPU and disk type)? -->

<!-- Any extra information that might be useful in the debugging process. -->

<!--- This is normally the contents of a `debug.log` or `config.log` file. Raw text or a link to a pastebin type site are preferred. -->

I think if you create the (datadir)/wallets directory manually and move your wallets into it, bitcoin should use this location, even on windows. For backwards compatibility, bitcoin will not create a (datadir)/wallets directory unless the entire datadir is new. But if the directory exists, it should use it regardless of platform. From -help output:

  -walletdir=<dir>
       Specify directory to hold wallets (default: <datadir>/wallets if it
       exists, otherwise <datadir>)

Oops, you're right.
