Proxy [[OwnPropertyKeys]] trap does not skip symbol keys when validating invariant:
* The returned List contains no duplicate entries.
info: |
Object.getOwnPropertyNames ( O )
1. Return ? GetOwnPropertyKeys(O, String).
GetOwnPropertyKeys ( O, type )
...
2. Let keys be ? obj.[[OwnPropertyKeys]]().
[[OwnPropertyKeys]] ( )
...
8. Let trapResult be ? CreateListFromArrayLike(trapResultArray, « String, Symbol »).
9. If trapResult contains any duplicate entries, throw a TypeError exception.
