Title: Automatically create indexes

This pull request supports Automatically create indexes made at [rails master branch](https://github.com/rails/rails/commit/ca0af8221a3b704fa289afe7030a96dc8cec8a95#activerecord/test/cases/migration/references_index_test.rb).

Actually, I do not think it's good implementation `if .. else` at the `add_index` method. Therefore I'd like this commit to be reviewed.
