### Steps to reproduce
Case 1 :
1. Create a calendar event (tried online and with Thunderbird)
2. Add attendees
3. Save
Case 2 :
1. Create a calendar event (tried online and with Thunderbird)
2. Save
3. Edit event.
4. Add attendees
5. Save
**Important note** : it fails only if one of the attendee is a nextcloud user with corresponding email in his account.
### Expected behaviour
In both case I expect event to be saved and user to receive an invitation by email.
### Actual behaviour
Web-interface : on save I see an infinite loading symbol and nothing is never saved.
Thunderbird : attendee is not added event is not saved.
In both case no event invitation is sent by email.
