LuceneSearcher - getAllMetadataFromIndexFor method processes even deleted documents

[josegar74]

LuceneSearcher.getMetadataFromIndex are used to retrieve directly the information from the index from the metadata id or uuid, the method uses LuceneSearcher.getMetadataFromIndex with a filter of type NoFilterFilter, but that filter seem retrieving even the deleted versions of the documents for a metadata (in case the index is not optimised), what can cause outdated information retrieved.

Changing the filter to the following seem working fine, not retrieving outdated versions of the documents:

Filter filter = new DuplicateDocFilter(new MatchAllDocsQuery());

@fxprunayre are you familiar with this code? Before doing a pull request want to confirm I'm not missing something about the usage of NoFilterFilter.
