Modify flaky test testRemotePublicationDisabledByRollingRestart

[shiv0408]

Description

Remove assertion on incompatible Diff Received is 0 after cluster manager flipped, as it is possible that one of nodes lags and receives a incompatible diff, then requests for full state after remote publication is disabled and we have shifted to publication on transport.

Ran the test 7k times to ensure no flakiness in the test.
