`Spond.get_event()` doesn't return 'scheduled' events, i.e. where invites are set to send in the future.
This is because get_event() calls get_events() with no parameters, which means include_scheduled defaults to False.
This filters out any events for which invites are set to send in the future (not 100% sure of behaviour with recurring events).
This is unexpected, but not sure if it can be considered a bug - maybe a documentation gap.
For me it would make sense if we could fetch a scheduled event from the ID.
There is a simple workaround - call get_events() with include_scheduled=True.
Then iterate through the list returned, for a match on uid.
I think the long-term answer is that get_event() should be changed to always take a sequence of events in which to look for the uid.
