Clean up ownership of sessions for ATScience

[bmann]

The ATscience sessions ended up being owned by atmosphereconf.org rather than atproto.science. I think we should go back and make all the sessions owned by atproto.science.

This will fix the lingering errors in the schedule and help VODs get aligned properly too. I’m going to push a fix for Travis’s talk time and hopefully we can get his recording up too.

Anyone reading this working on VOD jam can use the atproto.science event records already though 😉
