Can't delete birth date events

[ibahnasy]

Steps to reproduce

1. Add a birthdate to a contact.
2. Import/delete/re-import contacts same .vcf file.
3. Try to delete it from Calendar app but there is no option to do so.

Expected behavior

There should be an option in the event's settings but there isn't.

Actual behaviour

There is no option to delete the event in the settings and calendar is synced as read only to DAVx5 so can't delete it either from Android.
Every time you re-import the .vcf file, it add the same birth date event again to the database:

> select id from oc_calendarobjects where calendardata like '%Saad%'\G;
*************************** 1. row ***************************
id: 6
*************************** 2. row ***************************
id: 12
*************************** 3. row ***************************
id: 22
*************************** 4. row ***************************
id: 30
*************************** 5. row ***************************
id: 32
5 rows in set (0.000 sec)

Additional info

A workaround:

• I edited the affected contact and removed the birth date field.
• Deleted the events manually from the DB.
• Added the event again to the contact so it was added once.

> delete from oc_calendarobjects where id in (6,12,22,30,32);
