Fix #2778: Run CheckInfoReplication even with HeartbeatConsistencyChecks (#2784)

* Fix #2778: Run CheckInfoReplication even with HeartbeatConsistencyChecks

This is an issue identified in ##2778 and #2779 where we're not updating replication topology if heartbeat consistency checks are enabled because we exit the `if` structure early. This still runs that check if it's due in both cases, without changing the behavior of the result processor.

* Add release notes
