Description of problem:

When doing a search with a user (not admin), the API returns all objects the user has access to, not just the searched one like when doing with admin user.

Version-Release number of selected component (if applicable):
rhvm-4.5.3.2-1.el8ev.noarch

How reproducible:
Always

Steps to Reproduce:
1. Create 2+ Clusters (no need to initialize or anything, just have them there)
   engine=# select name from cluster;
     name   
   ---------
    Default
    Other
   (2 rows)

2. Create 1 additional internal user, give system permissions as Power User
   ovirt-aaa-jdbc-tool user add germano --attribute=firstName=Germano
   ovirt-aaa-jdbc-tool user password-reset germano --password-valid-to="2025-08-01 12:00:00-0800"

3. As admin user, search for 'Default' cluster, note only Default is returned.
$ curl -s -k -u "admin@internal:redhat" -H "Content-type: application/xml" https://rhvm.lab.toca.local/ovirt-engine/api/clusters?search=name%3D%22Default%22 | grep "^        <name>"
        <name>Default</name>

4. As "user" user, do the same search. Note both are returned
$ curl -s -k -u "germano@internal:redhat" -H "Content-type: application/xml" "https://rhvm.lab.toca.local/ovirt-engine/api/clusters?search=name%3D%22Default%22" | grep "^        <name>"
        <name>Default</name>
        <name>Other</name>

Actual results:
* incorrect search results returned
* as consequence ovirt_vm is broken when using non-admin user, as specifying cluster will actually pick the first from the list and not the searched one.

Expected results:
* same results returned as admin user

Additional info:

Looks like Search is not called at all for non-admin, goes to GetAllClusters
