Fix bug in v-add-letsencrypt-domain #2563 (#2744)

* Replace search_objects with an better method getting SSL_HOME var

If LE was enabled for multiple domains under the same users search_objects could return multiple times "same
same
same " 

Replacing it with get_object_value should solve the issue

* Add test for it
