Event series update: for event series that are reduced to one event

[troughc]

Current design:

Users can create multiple dates events for event series. On occasion, a user may delete all events but one from the multiple dates event, leaving ONLY one event in the event series. After this change is made and the event is saved:

• the event appears as a multiple date event in the List view with only one occurrence;
• multiple dates remains the selected option in the Dates section of the Event details view (and it will probably be set to Custom).

Event details view

Update - expected behaviour:

If a user removes (deletes) all dates except 1 from a multiple dates event, change this event to a single date event upon saving. In the list view, the event will look like a single date event:

The next time the user opens the event in the Event details, the Dates section will be set to single date:

note: Block the user from selecting same date as start and end date in date range selector.
