QP: Limit to deleted records for #deleted modifier at this level

Down in the DB's query_parser_fts procedure, we also know whether we're
in a deleted_search, and in those cases we skip all visibility and
similar testing accordingly.

QP: Repair edit_date, create_date, and bib_source filters

And also make records undeletable, where reingestion at undelete time
formerly balked in this manner:

> ERROR: duplicate key value violates unique constraint
> "record_attr_pkey" DETAIL: Key (id)=(1) already exists. CONTEXT: SQL
> statement "INSERT INTO metabib.record_attr (id, attrs) VALUES (NEW.id,
> new_attrs)" PL/pgSQL function "indexing_ingest_or_delete" line 129 at
> SQL statement
