Title: owner generator removed as columns and indexes already exists

Thanks for this gem!
Owner_id and owner_type are already added when the initial migration generator is run.
https://github.com/applicake/doorkeeper/blob/master/lib/generators/doorkeeper/templates/migration.rb#L8
So I removed the generator, template and spec as the generated migration would throw an error.
