ensure `ActiveRecord` models respect recent migrations in test suite
ensure `ActiveRecord` models respect recent migrations in test suite

when running `IN_DOCKER`, we run migrations on test suite startup. if
`ActiveRecord` classes have already been loaded, they don't respect those
updates. in order to ensure we're always using models driven by the latest
schema, force a reset for each `ActiveRecord::Base` inheritor.
