[6.x] Fix when passed object as parameters to scopes method

[wim-web]

When passing parameters to the callScope method, the behavior is not what you expect because it casts them to an array.

Via the __call method it works as expected.

// some instance
$now = Carbon::now();

// it works
SomeModel::query()->date($now);

// it doesn't work
SomeModel()::query()->scopes(['date' => $now]);

Fixed calling to Arr::wrap() instead of casting to an array.
