transformGraphElementPattern() and transformGraphPattern() ran their WHERE clauses through transformExpr() without ever applying coerce_to_boolean(), so a WHERE clause of any type was accepted and its bare datum was used as the qual, which resulted in wrong results without a diagnostic. Route both sites through transformWhereClause(), like every other WHERE clause, and add regression tests for the element-level and pattern-level cases.
