Events are not wired through the target object if they are on a base type

[AArnott]

The code that enumerates events on the target object in order to wire them up to the remote as notifications only looks at events directly declared on the leaf type rather than finding all on the type hierarchy:

vs-streamjsonrpc/src/StreamJsonRpc/JsonRpc.cs

Line 673 in b94d097

foreach (var evt in target.GetType().GetTypeInfo().DeclaredEvents)
