Do not notify failures on collisions

Currently, when a replication task is rescheduled due to a collision, it
is not marked as a retry.

However, the failure notification logic only suppresses notifications
for tasks explicitly flagged as retries.

This change adds an additional check to prevent failure notifications
for tasks that are rescheduled because of collisions.

The same logic was applied to the replication plugin with change Ibf1ca6247.
