Generator doesnt create migration for versions table

[westonganger]

I was running the normal generator in Rails 3.2.13 and it does not create the migration(s). When running the generator with the --with-associations flag it only generated the following migrations: CreateVersionAssociations and AddTransactionIdColumnToVersions which again is missing the other migration(s)

Update: seems like this was because the migration already existed in a previous migration. Maybe it would be good to show a message saying the migration already existed

Ok, so this is not a dupe of #459? Not sure how to show a warning message for duplicate migrations. If you have knowledge of how that is possible then please make a pull request.

rails does it, i think we should be able to. Relevant Rails source code is here https://github.com/rails/rails/blob/b9fcce3944653db5eb49119c134e8525e91f7aee/railties/lib/rails/generators/actions/create_migration.rb

If i get a chance I will take a look

Apologies @westonganger, a closer inspection at our migration generator found that this was actually not that difficult!
