accommodate HasEntityNamespace in context.all_selected_columns
Fixed regression in hybrid_property where a hybrid against a SQL function
would generate an ``AttributeError`` when attempting to generate an entry
for the ``.c`` collection of a subquery in some cases; among other things
this would impact its use in cases like that of ``Query.count()``.
Fixes: #6401
