db: drop redundant user_id index on email_sends

Browse source 
The composite ix_email_sends_user_kind_sent (user_id, kind, sent_at)
already satisfies leftmost-prefix WHERE user_id=? lookups on both
MariaDB and SQLite, so the standalone per-column index was dead
weight. Drop it before the migration ever lands in prod.
