d3c5e47391 wallet, refactor: Remove Legacy check and error (pablomartin4btc)
30c6f64eed test: Remove unnecessary LoadWallet() calls (pablomartin4btc)

Pull request description:

  Remove dead code due to legacy wallet removal.

  Leftovers from previous #32481.

  ---

  **Note**:

  While attempting to remove the legacy check in `CWallet::UpgradeDescriptorCache()` (which is called from `DBErrors WalletBatch::LoadWallet(CWallet* pwallet))`, I once again ran into the fact that `LoadWallet()` is used in two distinct scenarios — something I was already aware of:
  - Wallet creation – the upgrade is ignored here because no wallet flags are yet set; attempting to set a flag (ie `WALLET_FLAG_LAST_HARDENED_XPUB_CACHED` at the end of the upgrade function, if the legacy check is removed) would produce a failure (`DBErrors CWallet::LoadWallet()` -> `Assert(m_wallet_flags == 0)`).
  - Wallet loading – the upgrade proceeds correctly and the flag `WALLET_FLAG_LAST_HARDENED_XPUB_CACHED` is set.

  While revisiting this, I also noticed that some `LoadWallet()` calls in the wallet tests are unnecessary and I've removed them in the first commit.

  The following change in `UpgradeDescriptorCache()` could be done in PR #32636 as part of the separation between wallet loading and creation responsibilities.

  ```diff --git a/src/wallet/wallet.cpp b/src/wallet/wallet.cpp

   void CWallet::UpgradeDescriptorCache()
   {
  +    // Only descriptor wallets can upgrade descriptor cache
  +    Assert(IsWalletFlagSet(WALLET_FLAG_DESCRIPTORS));
  +
  -    if (!IsWalletFlagSet(WALLET_FLAG_DESCRIPTORS) || IsLocked() || IsWalletFlagSet(WALLET_FLAG_LAST_HARDENED_XPUB_CACHED)) {
  +    if (IsLocked() || IsWalletFlagSet(WALLET_FLAG_LAST_HARDENED_XPUB_CACHED)) {
           return;
       }
  ```
