This looks like a straightforward missing 'return true', but that doesn't explain why it wasn't detected earlier.
This was reported at https://www.mediawiki.org/wiki/Thread:Extension_talk:GuidedTour/Error_message_after_installing_GuidedTour:_%22Detected_bug_in_an_extension!_Hook_GuidedTourHooks...%22
The reason I didn't notice this is because it's not required since https://gerrit.wikimedia.org/r/#/c/70328/ . Now that I understand the issue, I'll still do this for backwards compatibility.
Change 96164 had a related patch set uploaded by Mattflaschen: Add return true to hook for back-compat with older core. https://gerrit.wikimedia.org/r/96164
