Allow stored expression types for new-chain expressions when set on the same AST node

When an expression has `new` in its receiver chain, only skip the stored
type lookup if the stored type came from a different AST node (e.g. assert
narrowing). If the stored type was set for the same AST node (e.g. inline
@var annotation), allow it through. This fixes @var overrides on
expressions like `return (new Defaults())->getFunctions()`.
