Improve error handling

I tried to fix skyderby/skyderby#434 , but ran into a couple of issues:

• I added a try-catch block on the line where the track scanner crashes if the timestamps are not in order. I couldn't figure out how to check the exception type to return a more specific error message when "ValueError: index must be monotonic" is raised.
• For some reason, the "Oops, something went wrong" that's shown on 500's in production doesn't pop up on my local. I assume that there is some other message when a 422 is returned?

And this is still showing up in the main program's logs:
