3bccd50ad2f384e6c8c97c7f44bda7ae0d777696 qt: Set flag after inital load on transaction table model (João Barbosa)

Pull request description:

  This fixes the case where transaction notifications arrive between `getWalletTxs` and `subscribeToCoreSignals`. Basically notifications are queued until `getWalletTxs` and wallet rescan complete.

  This is also a requirement to call `getWalletTxs` in a background thread.

  Motivated by https://github.com/bitcoin/bitcoin/issues/20241.
