Add useful projections for NXQL on DBS layer

Currently on MarkLogic/Memory/MongoDB implementations, we add three useful projections for each NXQL queries.
We add:

• ecm:id (or id key for MongoDB)
• ecm:parentId
• ecm:name

As the DBS layer needs it for some operation, like ordering on ecm:path, we want to inject these three projections in SelectClause given to queryAndFetch repositoy method.
