If there are repeated events in Google Calendar and one of them is changed, some or all the events disappear in KOrganizer.


Reproducible: Always

Steps to Reproduce:
1. Create new event in Google Calendar and make it repeated X times (Update KOrganizer to check that events you just created are visible)
2. Change only ONE of the repeated events in Google Calendar (After editing Google Calendar asks: "Would you like to change this event only, all events in the series or this and all following events in the series?" Click: "Only this event")
3. Update KOrganizer


Actual Results:  
Repeated events, or at least some of them, disappear in KOrganizer. In Google Calendar everything is ok. 

Expected Results:  
All the repeated events should be visible and one of them should have been updated.

If modifications are applied to all the repeated events in Google Calendar they are updated correctly in KOrganizer.
If the "not functioning" Google Calendar is exported to file and imported to KOrganizer events are correctly displayed.
