WIP: In activity table, remove user_id column and add activity_id #98

I tried to implement a DB migration, but I'm stuck with an error now. No idea why its happening, I didnt change any json or bool columns.

Checking lemmy_db v0.1.0 (/home/felix/workspace/lemmy/server/lemmy_db)
error[E0277]: the trait bound `serde_json::Value: diesel::deserialize::FromSql<diesel::sql_types::Bool, _>` is not satisfied
