[FIX] test_mail_full: fix expected kpi in sms mailing report

`replied_ratio` shouldn't be tested against bounced_ratio, neither
should be `opened_ratio` against `clicks_ratio`.
`_prepare_statistics_email_values` function returns list, whose last
two values are: `clicks_ratio` and `bounced_ratio` instead of
`opened_ratio` and `replied_ratio`. Also checking `replied_ratio` and
`opened_ratio` doesn't make sense, when testing sms.
