remove old queries

this whole theory of keeping old queries around was a better
theory than practice, especially given that we currently have nearly
60 open queries. We also change files and formats often enough that
the old queries really don't bring any value to the table.

remove support for soft delete on queries to prevent this debt from
building up further.
