## What changes were proposed in this pull request?
When SCM serializes an empty List into a Ratis log entry,
ScmListCodec.serialize writes a ListArgument proto with type =
`java.lang.Object` and zero value entries (the EMPTY_LIST sentinel). On replay
(follower sync or SCM restart), the old deserialize path unconditionally called
resolver.get("java.lang.Object"), which threw InvalidProtocolBufferException:
Failed to resolve java.lang.Object because Object is not a registered SCM codec
type. The guard short-circuits as soon as it sees zero value entries and
returns an empty ArrayList directly, which is the correct result regardless of
what the sentinel type string says
