Description

Previously in #3288 i fixed the commit bug of datacache, and i though it was a problem of memorystore, but now i realized the real problem is NeoSystem.StoreView is actually a readonly store view and all stores are supposed not having a snapshot. Thus having this pr to further extend the test cases demonstrating how StoreView and GetSnapshot works.

There is another issue that discoverd but not sure if it is designed to be so, which is the seek method of memorystore and dadacache has different processing logic. Please check the updated StoreTest and NeoSystemStoreGetAndChange
