Projects stuck importing when already exist on disk but not db

Description

When upgrading to postgresql@11, my database was basically restarted and reseeded, but all of the seed projects (i.e. gitlab-org/gitlab-test) were stuck "importing" or "forking". After some debugging, we tried cleaning out the gdk/repositories folder and rerunning bundle exec rake dev:setup and it worked.

It looks like running bunde exec rake dev:setup is not sufficient at resetting the gdk instance. Maybe we should introduce a task gdk dev-setup which will handle both the rake task and also resetting other things up the stack like the repositories folder.
