Cop idea: mutually exclusive FactoryBot traits

[pirj]

FactoryBot.define do
  factory :user
  trait :active do
    status { 'active' }
  do
  trait :inactive do
    status 'inactive'
  do
end

This allows for an undefined behaviour when being called as create(:user, :active, :inactive).
We should recommend making them sub-factories, not traits.
