FindCommerce writes unnecessary error message to log

Description

Steps to reproduce

1. Set up a site with EPiServer.Find.Commerce installed.
2. Set the appsetting episerver:FindListenOnCommerceRemoteEvents to false in the front-end site (emulating that you have multiple frontends and want to have a dedicated indexer).
3. Set the log level of the frontend site to debug.
4. Change/import catalog data into Commerce Manager.

Expected: No errors are logged.
Actual: Logs message like "EPiServer.Find.Commerce.CatalogContentEventListener - Failed to deserialize CatalogEventUpdated event args."
