Card migrations not initialized at wagn create time

With v1.11.5, immediately after setting up database.yml, "rake wagn:create" works fine but a subsequent "rake wagn:migrate" crashes.

It looks to me as though this is because wagn:create doesn't have anything similar to assume_migrated_upto_version for the card migrations. wagn:migrate tries to run RenamingForMenu, which assumes that there is a card called *content for it to rename to *structure, but the seed data has already been updated to create *structure in the first place.

Not that big a deal, since there's a workaround (just put the timestamps for the card migrations into schema_migrations_cards), but it's an irritant and probably a significant issue for non-rails-guys who don't want to understand the plumbing of activerecord.
