When you create an event and add an participant without sending an invitation and after that click on the event again, the switch "send invitation" is turned on.

Steps to reproduce:

1. Create event.
2. Add participant.
3. Switch "send invitation" to off.
4. Save the event.
5. CLick on the event again and click on "edit".
6. Go to "participants".

Actual results:
the switch for "send invitation" is turned on.

Expected result:
As the switch was turned off when creating the event it should have the same status when I look at the event again. First for consistency but also because otherwise I might think I sent an invitation and the other person knows about the event when they actually don't.
