Fix compilation errors after merging schema changes

After merging changes to the sql schema into your branch, some manual steps are required. We are working on automating some of them, but for now:

(1) Get Your Database’s Schema Up To Date

(1a) Quick and with data loss

• run yarn refresh-schema to drop your db’s contents and load a fresh schema from schema.sql

(1b) OR: Keep your data with evolutions

• conf/evolutions/ contains sql code to migrate your data to newer schema versions.
• to help you figure out which ones you need, you can optionally run tools/postgres/diff_schema.sh tools/postgres/schema.sql DB
• apply the evolutions in the correct order, e.g. by copying their content to a pgadmin query tool that is connected to your db and executing them there.

(2) Update the Slick access code

• run rm target/scala-2.12/src_managed/schema/com/scalableminds/webknossos/schema/Tables.scala so that the scala compiler subsequently recreates it from the now up-to-date schema in your db

Still trouble?

If the above steps didn't help. Try to run docker-compose down and repeat the above steps.
