NOTE: intended to be called from an event

Foo[1].aasm.current_state # => :closed
foo.aasm.current_state # => :closed
foo.save
Foo[1].aasm.current_state # => :opened
foo.aasm.current_state # => :closed
foo.close

foo = Foo[1]

it does not operate like an AR model and does not know how to postpone changes.
With Redis::Objects it's not possible to skip persisting - it's not an ORM,

(but actually it still does)
Writes state to the state column, but does not persist it to the database

def aasm_write_state_without_persistence(state, name=:default)
  aasm_write_state(state, name)
