Updated the instance to the newest lemmy 0.19.0 builds

I just update the instance to the newest lemmy-ui:0.19.0-beta.1 and lemmy:0.19.0-rc.1 builds, and as far as I can tell nothing blew up. =)

Oh and the site should work with logins now as well that was broken by an in between build that changed the database but not the front end to talk to it.
