Summary:                    [patch] Merging events for Exchange web service
doesn't work as expected, resulting in only one event in calendar
Description: 
I just noticed that when I have multiple events in EWS calendar, only one
is merged. And I found a strange behaviour of ast_calendar_merge_events().

I added a little debug output (in attached patch) and get this result:

AAA

-- in beggining of line means the event is removed from our internal
calendat, ++ means it was added and there should be also == which means it
was merged. Every action follows by UID of event, colon and name of event.

As you can, the event AAA is removed, event BBB is added, then removed and
then is event AAA added again, resulting in only event AAA being in
internal calendar.

I really don't know why is this happening, since UID is compared with
known events, and then is decided if we know if this event already exist or
not. And appereantly, the UIDs match, so I have really no idea why it
results in removing and adding the same event instead of merging.

And just for infomration, icalendar modul works as expected, merging
already known events.
