[SCI-5635] add a migration to fix broken steps, fix the api so it sets last_modified_by_id, minor step model refactor

migration fix

remove the conditoin for set_last_modified_by callback

set the last_modified_by_id in before_save callback (in case it is not set yet)

remove trailing spaces

Set last modified in protocl import service
