Make premium list saving run as a single transaction (#1480)

Browse source 
* Make premium list saving run as a single transaction

This fixes the bug where the new revision is saved, but then execution gets
halted for some reason (e.g. request timeout) before the entries finish saving,
which leaves the DB in a bad state with a new top revision containing zero
entries, thus making everything standard.
