Can't seed data in public schema with Rails 5.2

[archonic]

Steps to reproduce

Have a Rails 5.2.0.rc1 app with apartment installed and an excluded model Plan. Try to create plans in seeds.rb.

Expected behavior

Plans are created in the public schema.

Actual behavior

ERROR: relation "public.plans" does not exist

System configuration

• Database: (Tell us what database and its version you use.)
  Postgres with use_schemas. Using docker and codeship. Image is postgres:10-alpine.

• Apartment version:
  2.1.0. I'm using a fork to get around issue db:create fails #518.

• Apartment config (in config/initializers/apartment.rb or so):

  • use_schemas: (true or false)
    true

# Apartment Configuration
Apartment.configure do |config|

  # Add any models that you do not want to be multi-tenanted, but remain in the global (public) namespace.
  # A typical example would be a Customer or Tenant model that stores each Tenant's information.
  config.excluded_models = %w(
    Account
    User
    AccountsUser
    Plan
  )
  config.use_schemas = true
end

Rails.application.config.middleware.use Apartment::Elevators::Subdomain

• Rails (or ActiveRecord) version:
  5.2.0.rc1

• Ruby version:
  2.5

Full app is here:
https://github.com/archonic/limestone-accounts

This is my seeds.rb:

if Apartment::Tenant.current == 'public'
  plans = Plan.create([
    {name: 'Basic', amount: 900, currency: 'usd', interval: 'month', active: true},
    {name: 'Pro', amount: 1500, currency: 'usd', interval: 'month', active: true}
  ])
  puts "CREATED PLANS #{plans.pluck(:name).join(', ')}"

  accounts = Account.create([
    {name: 'Limestone', subdomain: 'limestone', plan_id: Plan.last.id, current_period_end: 5.years.from_now, trialing: false, past_due: false, unpaid: false, cancelled: false}
  ])
  puts "CREATES ACCOUNTS #{accounts.pluck(:name).join(', ')}"
end

if Apartment::Tenant.current == 'limestone'
  admin_user = CreateAdminService.call
  puts 'CREATED ADMIN USER: ' << admin_user.email
end

Backtrace:
