Title: Fix serialized field returning serialized data after update_column

Fixes the issue reproduced in the first test in `activerecord/test/cases/serialized_attribute_test.rb`.

I'm a little unsure of the approach in `activerecord/lib/active_record/attribute_methods/write.rb`, if anyone has a better idea I'd love to hear it.
