Support terms with the same name in a tree structure and multi-parent terms

I think the priority on this one should be higher - Structure Sync doesn't provide mcuh value if it won't import the whole taxonomy in this common scenario.

Patch test failed

3 years ago it worked 😂 wish I remembered the project it was for.
Looks like maintainers missed this.

Looks like this proposed solution includes some client-specific code:

+            if ($taxonomy['name'] == 'Residency' && $taxonomy['vid'] == 'campaign_goal') {
+              $parent_terms = $storage->loadByProperties(['uuid' => $parent_uuids]);
+            }
