Calendar app: birthdays are synced multiple times
I have /e/OS 1.0-20220526188859 on a Samsung S7
each time we load the contacts onto a phone again (this happens when switching to a new /e/os device for example, or reinstalling the OS), a new list of contact birthdays events gets triggered, leading to duplicates.
