Motivation: 32563bfcc129ef9332f175c277e4f6b59fd37d8c introduced a regression in which we did now not longer discard the messages after we handled an oversized message. Modifications: - Do not set aggregating to false after handleOversizedMessage is called - Adjust unit tests to verify the behaviour is correct again. Result: Fixes https://github.com/netty/netty/issues/9007.
