Subject: [PATCH] fix deprecation warning for at least php 8.1.6

running `vendor/bin/phpunit` on at least php version 8.1.6 results in multiple
warnings that state:

Deprecated: ltrim(): Passing null to parameter #1 ($string) of type string is deprecated in .../Coders/Model/Model.php on line 505

add a conditional to check the argument for null before using it to build parentClass
