Saved Searches : Save old records

Commit 5be0de0d introduced the idea of moving up old saved searches to make
room for custom queues - but failed to account for cases where the system
has more than 30 saved searches.

This commit addresses the issue by just re-inserting the old records after
queues are imported.
