Ticket 50053 - Subtree password policy overrides a user-defined password policy
    
    Bug Description:
    	When an entry contains an attribute that is also defined by a cos definition
    	a specifier defines which values win: the real values that are in the entry or the
    	virtual values that are cos defined.
    	The specifier 'default' means that the real values are the winners (returned).
    	'operational-default' has the same behavior but just specify that the attribute
    	is operational.
    	The bug is that when real values exists, the 'operational-default' specifier
    	drops the real values in favor of the virtual ones.
    
    Fix Description:
    	Change the test, so that real values are not kept for 'operation-default'
    	Note: the full routine cos_cache_query_attr looks quite messy and error prone
    	It would be nice to rewrite it when we have time
