`findItemByTypes` doesn't properly filter out blocked items

[patriksh]

Describe the bug Newly rewritten function findItemByTypes doesn't properly filter out blocked items.

In Osclass 3.x by default blocked items were filtered out from all types other than "all". https://github.com/osclass/Osclass/blob/b1c67a2bd623748a3090b66d8ac5a0baf78172c8/oc-includes/osclass/model/Item.php#L560-L564

In Osclass 5.x that's not the case, hence issues such as displaying blocked items on public profile happen. https://github.com/mindstellar/Osclass/blob/561833cf7c2e7f820eb4808d37367b4c93ad0ccc/oc-includes/osclass/classes/model/Item.php#L559-L592
