These are leftovers from when fizzy-saas was a standalone repository. Since it was moved into fizzy as a path gem, the production bundle uses Gemfile.saas at the root. Nothing references saas/Gemfile. Also removes saas/bin/rails (references nonexistent test/dummy app) and saas/bin/rubocop (references nonexistent saas/.rubocop.yml), both equally defunct standalone-repo leftovers.
