temporarily remove dependency on schemup, as it has not been published yet
ensure schemup schema used for migrations use the same connection as the storm store it's created from

This allows mixing migrations using raw SQL statements and migrations
using ORM (warp.runtime.avatar_store) to be used together in 1 run.

fix idle transaction created by the migration process
add an index to warp_session.touched so that looking for old sessions will be faster
