Fix NXQL ecm:isLatestVersion = 0 and ecm:isLatestMajorVersion = 0

Both of those:

SELECT ... WHERE ecm:isLatestVersion = 0
SELECT ... WHERE ecm:isLatestMajorVersion = 0

don't match enough documents. They should match all documents which are not the latest, including non-versions.

This is also needed for semantic compatibility with CMIS.
