We already test "arguments" and "length" a few lines above using "in" expression. For the negative tests like this, "in" expressions are stronger tests. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7970#note_102575

For testing exposed properties, using `test_own_props` would be better. Additionally, it would be good to test the actual value of the property (probably `null` in this case). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7970#note_102576

I had to add a fix for builtin props filling, else we wouldn't be able to test the patch. There's more prop filling fixes I planned to send on next MR (but I moved this one now since it was needed).
