Do not call callbacks when they are disabled #162

I've been using state_machine with ActiveRecord and in some instances am using ActiveRecord::Observers.disable to turn off observers (for instance, to isolate certain model behaviors during tests). state_machine's definition of Observer.update_with_transition does not check for disabled_for? before using the send method to call the callback.

I added test cases to the ActiveModel and ActiveRecord integration tests to test the behavior and changed the update_with_transition method to match the current implementation in ActiveModel itself.

Hey @joelind -

Thanks for reporting this and providing a fix! As it turns out, the problem is that ActiveModel just isn't properly detecting the disabled list of observers on the object -- state_machine doesn't need to actually implement those checks. I've gone with a different implementation that should resolve this issue in the same manner.
