b1d2c771d4 wallet: Check for descriptors flag before migration (Andrew Chow)
8c127ff1ed wallet: Skip key and script migration for blank wallets (Andrew Chow)

Pull request description:

  Blank wallets (wallets without any keys are scripts) are being detected as already being descriptor wallets even though they are not. This is because the check for whether a wallet is already a descriptor wallet uses the presence of a `LegacyScriptPubKeyMan` which is only setup when keys or scripts are found. This PR resolves this issue by checking for the descriptor wallet flag instead and subsequently skipping the keys and scripts part of migration for blank wallets.

  Fixes the issue mentioned in https://github.com/bitcoin/bitcoin/pull/28868#issuecomment-1809641110
