    Ensure migration file names are unique to avoid caching errors

    This patch requires migration files to include a prefix (expand,
    migrate, contract) in order to keep them unique and prevent a bug
    related to caching. Here is the standard format:
    [version]_[prefix]_[description]

    For example:
    * 001_expand_new_fk_constraint.py
    * 001_migrate_new_fk_constraint.py
    * 001_contract_new_fk_constraint.py
