[TASK] Streamline backend password reset log message

The current backend password reset log message misses a `}` and logs
the `user_id` if a password has been reset successfully. Logging the
`user_id` is however not inline with other user related log messages,
where always the `username` is logged.

This patch streamlines the log message with other user related log
messages by including the `username` instead of the `user_id`.
