Add a check beforehand that:
- If
self.original_storagedoes not contain the key, - and the to-set-value is the same as the current value.
Skip inserting into the original_storage.

If self.original_storage does not contain the key,
That's whatif let Vacant(e) = self.original_storage.entry(...)does, which was recommanded by clippy instead ofcontainstheninsert.
and the to-set-value is the same as the current value.
Yeah, can add this check to not insert for same value as original.

Use self.storage here to keep it consistent.

Cannot use self.storage as we're already borrowing self with self.original_storage.entry. Seems better to keep <AccountStorages<T>>::get than fetching the value every time even when the entry is not vacant.
