Fix issues with deserializing mappings when retrieving mappings from the server.
We need to make sure that we can deserialize the interfaces on the RootObjectMapping, which requires specifying ResolveAsTypeConverter on all the appropriate interfaces. I added a test as well, though I'm not sure it's in the right place, and I added a Deserialize function on TestElasticClient to make it easier to roundtrip the serialization.
