Laravel 10 compatibility

[vroomfondle]

Laravel is calling getDates() and that's causing the following error because the $dates attribute has been removed in Laravel 10:

TypeError : in_array(): Argument #2 ($haystack) must be of type array, null given
 /var/www/api/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Concerns/HasAttributes.php:1089
 /var/www/api/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Concerns/HasAttributes.php:961
 /var/www/api/vendor/thybag/pseudo-model/src/Models/PseudoModel.php:311
 /var/www/api/tests/Api/v2/Integration/Mappers/SecurityMapperTest.php:95
 /var/www/api/vendor/laravel/framework/src/Illuminate/Foundation/Testing/TestCase.php:174
 

The Laravel 10 implementation of getDates() just returns the created/updated timestamps or an empty array. I've made PseudoModel just return the empty array.
