update on_skip to adjust for node that do not have schema

[ChenyuLInx]

resolves #10029

Problem

SavedQuery node do not have schema field, this cause on_skip to fail.

Solution

During the on skip, we optionally get schema field.
The other way is to add schema to the saved_query node, but that is not a useful piece of information for this node.
