overwrite select columns by a criteria

When I have a criteria like:
```php
public function apply($model, RepositoryInterface $repository)
{
return $model->leftJoin('deals', 'deals.country_id', '=', 'countries.id')
->addSelect(\DB::raw('count(deals.id) as deals_count'))
->groupBy('countries.id')
->orderBy('deals_count', 'desc');
}
```

then we cant specified columns when `->all($columns)` is fired.

```php
$countryRepositoryEloquent->resetCriteria();
//$countryRepositoryEloquent->select(['countries.*']);
$countryRepositoryEloquent->pushCriteria(CountryWithDealsCountCriteria::class);

return $countryRepositoryEloquent->all();
```

A fields pushed in Criteria overwrites default columns from a model :(
