Remove an empty line from generated migration

Browse source 
Currently, if you run `rails g migration remove_column_from_models`,
there is an empty line before `remove_column` line because we forgot to
use `-%>` in the template:

    $ bin/rails g migration remove_title_from_posts title:string
          invoke  active_record
          create    db/migrate/20200114061235_remove_title_from_posts.rb

    $ cat db/migrate/20200114061235_remove_title_from_posts.rb
    class RemoveTitleFromPosts < ActiveRecord::Migration[6.1]
      def change

        remove_column :posts, :title, :string
      end
    end

This commit adds the missing `-` in front of `-%>` to make it removes
the empty line.
