calendar: Fix inclusion of zero-length events

Browse Source 
Events with a date time (not just a date) where the end time is missing
or matching the start time were considered to not overlap the selected
interval if they were happening on the start time of the interval. This
was causing such zero-length events to be omitted from the calendar if
they were starting at 0:00.
