(fix): CI — testTransformations: preserve placeholders in transformed SQL

The transformation rewrote the prepared SQL to "SELECT 1", but SQL.php's
getDocument still calls bindValue(':_uid', $id) (and ':_tenant' for
sharedTables). PDO throws HY093 because the rewritten query has no
placeholders.

Wrap the original query as a derived table with WHERE 1=0 instead. The
inner query keeps the :_uid / :_tenant placeholders so the bindValue
calls match, while the outer WHERE forces zero rows so isEmpty() still
asserts the trigger was applied.
