XD-639: Use better msg when trying rm w/o --recursive
XD-1268 Removed unused accepted media types from  MessageBus
simplified (de)serialization method names
Add Redis queues cleanup after tests

- Added cleanup logic to delete Redis queues after test run
in RedisSingleNodeInitializationTests and RedisTestMessageBus

Call application.close() appropriately

- Since the RedisTestSupport's cleanupResources() would
destroy the Redis connection factory, closing the application
at the cleanup() help destroying all the bindings' endpoints
before the connection factory is destroyed.
