Call log_process_action to get the right status code (devise)

[quentindemetz]

This is a revival of #194 by @clupprich based on the latest master.

Devise did implement a fix (https://github.com/heartcombo/devise/pull/4375) for this, but which was quickly reverted (https://github.com/heartcombo/devise/pull/4804).

Locally with devise 4.8.1 and lograge 0.12.0 some of my logs are still populated with status: 0. I've been able to reproduce this locally, and can confirm the issue is fixed with this change.
