Ticket 47350 - (Cont.) Allow search to look up 'in memory RUV'
    
    Bug Description:
    	Returning the in memory RUV in place of the DB RUV is not
    	systematically the right thing to do.
    	For administrative operations (like total update), the server
    	wants to access the real DB RUV and not the in memory RUV.
    
    Fix Description:
    	The fix checks if the search is an internal search.
    	if it is it returns the DB RUV (tombstone)
