error migrating to/from conduit with conduit_compat disabled

Browse source 
In the future, we'll probably want to implement real support for
changing the admin bot userid. For now, just error so things don't break
in confusing ways.

We should note in the docs when creating a new server, that if you don't
enable conduit_compat you won't currently be able to migrate away.
