When using eZ Find 'subtree_array' in a fetch, the returned results always point to their respective main parent nodes.Non-main nodes are not considered.

Steps to reproduce:

1. Create the following content structure:

Article 1 (node_id: 158, main location)
	Article 1.1
Article 2 (node_id: 160)

2. Add "Article 2" as a second location for "Article 1.1". "Article 1" is still the main location. You should have the following structure:

Article 1 (node_id: 158, main location)
	Article 1.1
Article 2 (node_id: 160)
	Article 1.1

3. Search for "Article 1.1" in "Article 1" => OK, search result points to "Article-1/Article-1.1".

Used this fetch on search.tpl template ('eng' frontend siteaccess):

{set $search=fetch( ezfind,search,
                        hash( 'query', $search_text,
                              'subtree_array', array(158) )
                             )}

Then went to "example.com/eng/content/search" and searched for "Article 1.1". Result - "Article 1.1" - points to "Article-1/Article-1.1", which is OK.

4. Search for "Article 1.1" in "Article 2" => OK, search result points to "Article-2/Article-1.1".

Used this fetch on search.tpl template ('eng' frontend siteaccess):

{set $search=fetch( ezfind,search,
                        hash( 'query', $search_text,
                              'subtree_array', array(160) )
                             )}

Then went to "example.com/eng/content/search" and searched for "Article 1.1". Result - "Article 1.1" - points to "Article-2/Article-1.1", which is OK.

5. Change "Article 1.1" main location from "Article 1" to "Article 2":

Article 1 (node_id: 158)
	Article 1.1
Article 2 (node_id: 160, main location)
	Article 1.1

6. Redo steps 3 and 4 => Incorrect, each search result now points to "Article-2/Article-1.1".
