Skipped tutorial step is not logged in funnel data (UploadWizardStep) if skipped due to campaign configuration. It is logged if skipped due to user preferences, though.
Turns out https://gerrit.wikimedia.org/r/#/c/314024/ didn't fix this.
It even made it worse: similar to how tutorial step was already skipped completely if config told it to skip (config.tutorial.skip), it would not also do so when user preference was set to skip (mw.user.options.get( 'upwiz_skiptutorial' )).
So if tutorial was skipped, most of the time nothing at all would be logged.
Patch coming up.
