PHP Deprecation: Using null as array offset in CategoryRepository::findTree()

[bikar-can0199]

Bug Report

Current Behavior

When calling CategoryRepository::findTree(), a PHP runtime deprecation notice is thrown:

PHP Runtime Deprecation Notice: Using null as an array offset is deprecated,
use an empty string instead in
vendor/georgringer/news/Classes/Domain/Repository/CategoryRepository.php line 114

Expected behavior/output

No deprecation notice should be thrown. The null check should happen before using the value as an array offset.
