Motivation: DefaultChannelPipelineTest creates a channel and completes promises, but does not register this channel to an event loop. This is generally an illegal state for DefaultPromise, and the 4.1 branch correctly registers the channel in all of these cases. Modifications: - DefaultChannelPipelineTest should register the channel to an EventLoopGroup before completing a promise generated by that channel Result: DefaultChannelPipelineTest is more correct and consistent with 4.1.
