As a Wikidata editor, I want to create and edit items without getting conflict reports for pages that don’t exist.
**Problem:**
The Wikidata term store (aka new term store, normalized term store) contains some rows for deleted items.
**Example:**
An editor tried to set the Spanish label of an item to «Nicki Nicole» and the description to «cantante argentina», but got an error that “Item Nicki Nicole (Q67179790) already has label "Nicki Nicole" associated with language code es, using the same description text” ([project chat permalink](https://www.wikidata.org/w/index.php?title=Wikidata:Project_chat&oldid=1281510917#Label/description_conflict_with_a_deleted_item?)); however, the page [Q67179790](https://www.wikidata.org/wiki/Q67179790) was actually deleted on 12 September 2019.
Querying the term store on Toolforge, we can see that the rows still exist which allowed Wikidata to detect the “conflict”, and also to render `{{Q|Q67179790}}` using the label of the deleted item:
```lang=mysql
MariaDB [wikidatawiki_p]> SELECT wbit_item_id, wby_name, wbxl_language, wbx_text FROM wbt_item_terms JOIN wbt_term_in_lang ON wbit_term_in_lang_id = wbtl_id JOIN wbt_type ON wbtl_type_id = wby_id JOIN wbt_text_in_lang ON wbtl_text_in_lang_id = wbxl_id JOIN wbt_text ON wbxl_text_id = wbx_id WHERE wbit_item_id = 67179790;
