Empty session displaying on Day 1 at 11am after the 11am speakers

Just before lunch at 12pm and after the 11am speakers there is an empty agenda item that just says: "at Location TBD"

I think data is being fetched from the web site and it appears there may be an empty session at the back end?

Here are screenshots of what is seen in the app and the data in the debugger when tapping on that item. Can we check the back end to see if there is an empty session or perhaps its the empty workshop data that is creating this empty data?

This should be fixed by #29.
