dont include types in NSB in message conventions

Unfortunately this would only handle 2 of our assemblies, how about the others? Specially Azure.
Another option would be to use the PublicKeyToken, since all our assemblies are signed with the same SN key I think it would work.
We use that technique in the `AssemblyScanner`.

The other think I was thinking about is, will this still work?
```c#
IHandleMessages<IMessage>
```
