Returns the value of the aasm_column - called from aasm_current_state

If it‘s a new record, and the aasm state column is blank it returns the initial state:

  class Foo < ActiveRecord::Base
    include AASM
    aasm_column :status
    aasm_state :opened
    aasm_state :closed
  end

  foo = Foo.new
  foo.current_state # => :opened
  foo.close
  foo.current_state # => :closed

  foo = Foo.find(1)
  foo.current_state # => :opened
  foo.aasm_state = nil
  foo.current_state # => nil

NOTE: intended to be called from an event

This allows for nil aasm states - be sure to add validation to your model
