Serialize/Deserialize list for multi-instance query result.

[jangalinski]

Query and Result and serialized with avro ... but since we are using a multi instance response-type, the conversion takes place on array list, which fails:

org.axonframework.axonserver.connector.query.AxonServerNonTransientRemoteQueryHandlingException: An exception was thrown by the remote message handling component: Cannot build a converter to convert from java.util.ArrayList to [B

This problem is similar to json/jackson serialization with lists, where we need to include the FQN of the result type.

The obvious workaround is to define a list schema for the multi instance return type, but it would be nice/intersting if we could find a generic solution, maybe using multiple avro serialized bytes in a collection.
