### How to test
1. Make sure you have wikibase extension tree on https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Wikibase/+/517148
2. You should have the following in LocalSettings.php:
```lang=php
$wgWBRepoSettings['tmpPropertyTermsMigrationStage'] = MIGRATION_WRITE_NEW;
$wgWBClientSettings['tmpPropertyTermsMigrationStage'] = MIGRATION_WRITE_NEW;
// for convineince during the test, bypass caching
$wgMainCacheType = CACHE_NONE;
$wgParserCacheType = CACHE_NONE; # optional
$wgMessageCacheType = CACHE_NONE; # optional
```
3. Create a property, or use an existing property
4. Delete all terms of that property from wb_terms table (you can use sql repl `php /var/www/html/maintenance/sql.php` to execute sql):
```lang=sql
delete from wb_terms where term_full_entity_id = "Pxxx"; -- replace Pxxx with the property full id
```
5. go over the use cases.. properties should render properly.
### Use Cases to test
- Rendering property labels in statements blocks (uses PropertyLabelResolver).
- Rendering property labels & descriptions in search results when searching for a property when adding a statement (users PrefetchingTermLookup).
