pgsql: Refine query jumbling handling for CallStmt

Refine query jumbling handling for CallStmt

Previously, all the nodes of CallStmt were included in the jumbling,
causing a duplicate in the computation as the transformed state of the
CALL query was included as well as the parsed state (transformed
FuncCall with all the input arguments and potential output arguments).
