XWIKI-10003: Cache problem with Solr facet filter results count
* When a default document translation with default locale != ROOT was deleted from the database the Solr indexer failed to delete the corresponding Solr document because the Solr document ID was computed without the locale (since the real locale isn't accessible anymore after the XWiki document is deleted from the database).

(cherry picked from commit ae6db9ea67c5119a9bacd8d02ce25aff5ca28e25)
