Add a test for error paths: error data must be present on the message itself. There are 2 (4, actualy) error paths not covered, since they rely on code present in queues (commit after activity execution), and it's not possible to extract message object after error was processed, so it cannot be unit tested. Message commit must be moved to Message.__call__ and ActivityTool.invokeGroup for those cases to be testable.
