calendar events shouldn't disappear from indicator until event ends

[Bill Filler]

This is stripped out from previous bug: lp:1557571

> Also, the indicator sometimes gets the wrong time until an event is scheduled to start. As an example, I had an event scheduled for 23:50. At 23:43 I pulled down the indicator and it said 7 minutes 'till. At 23:45 I tried again and it still said 7 minutes. I checked again at 23:47 and it said 3 minutes till. I checked again at 23:50 and it still said 3 minutes. At 23:51 the item disappeared, even though the event was an hour long. So, it updates infrequently and doesn't show events while they're active (except for the first minute).

Basically the event should not be removed from the indicator until it's entire duration is over. Currently it's removed the minute after it starts, but probalby should stay and say "In progress" or something?

Adding design here for guidance.

Bill, that's the same issue than bug #1302004 right (which has an approved branch)?

Status changed to 'Confirmed' because the bug affects multiple users.

Seb is right, this is a dupe of https://bugs.launchpad.net/ubuntu/+source/indicator-datetime/+bug/1302004
