"Number of items" in Calendar properties non-zero even after deleting all items
Steps to reproduce:
1. Sync a large number of Google calendar items to the default calendar using vdirsync until it starts failing due to rate limitations.
2. Remove all items using cadaver: rm *
3. Check "Number of items" in the Calendar web UI
It shows 0.
It shows a positive integer. About 10x the number of items that were matched during `rm *`.
