[FIX] tools: keep image option related attributes

- Change an image option in mass mailing editor (e.g. Quality)
- save
- edit -> The option can't get the new applied value.

The body_arch's field used in mass mailing editor is
sanitizing attributes and as a consequence, option related data
attrs are removed on save.
