Title: Moved #create! method from Validations to Persistence module

Not sure why `create!` is defined in Validations. Maybe historical reasons, but all other methods like `save`, `save!` and `create` defined in Persistence and only overwritten in Validations. That is why moved `create!` to Persistence as well.
