Merge #19323: gui: Fix regression in *txoutset* in GUI console

314b49bd50906c03911d2b17a21a34685a60b3c8 gui: Fix regression in GUI console (Hennadii Stepanov)

Pull request description:

  The regression was introduced in #19056: if the GUI is running without `-server=1`, the `*txoutset*` call in the console returns "Shutting down".

  Fix #19255.
