Deleting an addressbook does not seem to delete its birthday calendar entries

[gohrner]

Not sure if this issue is assigned to the right component... Possibly it belongs to Contacts or Calendar app?

Steps to reproduce

1. Import a vcard address book
2. Delete this vcard address book
3. Repeat the previous step three times (which I did because of vcard import problems...)

Expected behaviour

The birthday calendar should have one entry for each contact.

Actual behaviour

The birthday calendar has three entries for each contact.

Are you using external storage, if yes which one: local

Are you using encryption: no

Are you using an external user-backend, if yes which one: local users only

Addendum: Of course those entries persisted, they were not cleaned up by the cron job.

I now removed the birthday calendar and thought that the cron job should re-create it on its next run, but it does not seem to do so... Is there anything else I need to do to recreate the birthday calendar (with proper contents this time, of course...)?

GitMate.io thinks possibly related issues are #11305 (Deleting contacts not necessarily delets birthday-entries in birthday calendar), #4451 ("Delete Calendar" Issue), #10864 (Automatically delete old calendar events), #3003 (Disable birthday contacts calendar generation for user), and #1506 (Birthday events created while importing contacts should be deleted if addressbook containing the corresponding contact is deleted).

Duplicate of #1506, sorry. :-/ Didn't find this issue while searching for a previous report.
