Sergey Biryukov 91feaf04af Tests: Correct assertion in Tests_DB::test_prepare_incorrect_arg_count().
On failure, `wpdb::prepare()` returns either an empty string or `null`, not `false`.

The test only passed accidentally due to `assertEquals()` not performing a strict type check.

Follow-up to [41662].

See #38266.
