fix: repo item type fqdn if namespace equals

[theuargb]

Once SearchResultsInterface and ItemInterface share the same namespace, reflection returns $resultItemsType relative to $resultType, while the module requires FQDN

Fixed behavior:

$resultType = Vendor\Module\Api\Data\SearchResultsInterface
$resultItemsType = Vendor\Module\Api\Data\ItemInterface[]
