[Oracle] Don't report a cancelled card database update as successful (#7082)

* [Oracle] Don't report a cancelled card database update as successful (#3470)

Took 3 minutes

* [Oracle] Only report cancel when nothing was saved yet

Rejecting the wizard after SaveSetsPage or a download page already
wrote the database to disk still replaced cards.xml on disk, but
wasCancelled() forced exit code 1 so Cockatrice skipped the reload.
Track successful saves with OracleWizard::markDatabaseSaved() and only
treat a cancel as a failure when nothing was saved.

* [Oracle] Restore updater stderr in card update error dialog
