Flight/Event/Train reservation does not check calendars if event exists

[kesselb]

Steps to reproduce

1. Open an email with a flight reservation (e.g. from booking)
2. Add event to calendar => "Event imported into CalendarName"
3. Click again on "Add event" => "Could not import event"

Expected behavior

Check if the event already exists in the calendar like for imip messages.

Actual behavior

An error when trying to import an event that already exists.

Hey,

Are you trying to import the same event twice? Or is this a case of a split booking (two invitations one for leaving and the other for return) with the same ID?
