[fix](test) Fix compile error in ReplicaTest: cannot instantiate abstract Replica

The testBaseReplicaSchemaHashReturnsNegativeOne test tried to instantiate
abstract class Replica directly, causing a compile error. Merged the
no-op setSchemaHash assertion into the existing CloudReplica test, which
exercises the same base-class code paths since CloudReplica inherits
getSchemaHash()/setSchemaHash() without overriding them.
