Title: Fixes bug in calling index_name method

While migrating down any migration like the following:

```ruby
class AddIndexesToDb < ActiveRecord::Migration
def change
add_index :users, [:id, :role]
end
end
```

the remove_index method calls index_name method incorrectly which is fixed in this pull request.
