Add primary_key to issue_index (#16813)
Make the group_id a primary key in issue_index. This already has an unique index and therefore is a good candidate for becoming a primary key. This PR also changes all other uses of this table to add the group_id as the primary key. Fix #16802 Signed-off-by: Andrew Thornton <art27@cantab.net>
