Description
We currently don't have support for key-only payloads bigger than the KEY_HASH length.
Receiving such kind of messages produces a segfault in DataReaderHistory.
This PR adds a regression test reproducing the issue, and fixes it by considering the incoming change as irrelevant.
It has been done this way so it is acknowledged in reliable topics, thus avoiding the offending data to be resent.
