Save pre-saved changed_attributes.

[treby]

Hi!

I use update_document method in after_commit for transaction. In a controller, if we call save method twice or more times in transaction block, before_save overwrites @__changed_attributes variable. So elasticsearch does not reflect entire changes.

So I tried to keep the variable before overwrite.

Hi, thanks for the catch! Can we add a test for this? I think an integration test is fine in this case.

Thank you for your response! I will write test for this change.
