False positive - Method return typing changed when class in the same namespace

[ihor-sviziev]

I've seen few times when SVC check was complaining about changed return type, when actually it wasn't.

Example taken from magento/magento2#27980 here https://github.com/magento/magento2/pull/27980/files#diff-fe16896d208c3ab2d52fccbbf7a5eaebR113:

             $value = null;
         }
         return parent::where($cond, $value, $type);

Actual result

Result is following:

Level	Target/Location	Code/Reason
MAJOR	Magento\Framework\DB\Select::where/lib/internal/Magento/Framework/DB/Select.php:115	M120 [public] Method return typing changed.

Expected result

Return type isn't changed.

Test complaining that return type has changed, but it actually not, as class Magento\Framework\DB\Select actually is THE SAME class as Select as it in the current namespace.

• return type was replaced to import with alias - https://github.com/magento/magento2/pull/27129/files#diff-9a6bbd63a553b9d289b089830857e6d7L195
