Fix ghost Gallery entries in journal timeline and public share

- deleteEntry now deletes photos with the entry instead of moving them
  to a hidden Gallery entry that becomes an undeletable ghost
- deletePhoto cleans up empty Gallery entries after last photo removed
- getJourneyFull and getPublicJourney filter out empty Gallery entries
  so existing ghosts are hidden in both internal and shared views
