Stripping quotation marks of argument default value

[zingimmick]

When LaravelSetList::LARAVEL_60 applied, the code changes as below:

-DB::connection($connection)->table($table);
+DB::connection($connection)->table($table, 'null');

Expected Behavior:

-DB::connection($connection)->table($table);
+DB::connection($connection)->table($table, null);
