Stop trying to fetch events with event_id=None. (#5753)
`None` is not a valid event id, so queuing up a database fetch for it seems like a silly thing to do. I considered making `get_event` return `None` if `event_id is None`, but then its interaction with `allow_none` seemed uninituitive, and strong typing ftw.
