Simplify shouldDelegateList 

When ResourceVersionMatch is set to NotOlderThan, there is no need to handle continue or resourceVersion="".
The validation in apimachinery will not pass and return:
* "resourceVersionMatch is forbidden when continue is provided"
* "resourceVersionMatch is forbidden unless resourceVersion is provided"
