Merge #12845: Trivial: Add logging line in init.cpp that was accidentally removed with #10762

23abfb7b7f added logging line back that was accidentally removed with #10762 (Steve Lee)

Pull request description:

  I made the change based off of the DummyWalletInit refactor commit. I can rebase once that is merged.

  I built with wallet disabled and debug enabled. I then confirmed in the debug output that the logging line I added back indeed printed.
