default to null

 `_deprecated_hook`, the function responsible for logging an error when an
 old hook is called, uses `is_null` to check if a `$replacement` was
 provided.

 The problem is that `$replacement` defaults to `false` (instead of `null`)
 on `apply_filters_deprecated` and `do_action_deprecated`, displaying the
 `Use %3$s instead.'` message without any value.
