[FIX] mass_mailing: Do not alter method signature

Before this patch, this method was altering the signature of its parent method, moving the position of `failure_type` to 1 and making the other 2 arguments kw-only.

It seems this accidentally didn't break anything because all calls happened to be done in kwarg mode. However, it's very possible that a downstream module that is not based on `mass_mailing` and makes positional calls gets broken when `mass_mailing` is installed.

The fix is to respect original method signature.
