Recurring event: cover image, categories & tags only apply to the first occurrence

The rest of the occurrences in the series end up with no cover image, no categories, and no tags. **Where:** Recurring event creation. **Expected:** The cover image, categories, and tags set when creating the series should apply to all occurrences, not just the first one. **Steps to reproduce:** 1. Create a recurring event. 2. Set a cover image, add categories, and add tags. 3. Save. 4. Open one of the later occurrences — it has no cover image, categories, or tags.
